just need some opinions on what muffler to run,currently have hooker turbo mufflers,but want to change out to more aggresive sounding and flowing muffler,flowmasters? dynamax? pypes?

thrush? ;) just kiddin!!

any opinions,I now got 2 1/4 exaust,2 1/8 hooker pro comps,exhaust is in the stock type location,dont want all new exhaust,just a muffler change--opinions welcome please--67rat

I'm a big fan of Flowmasters sound. I have installed 2 systems on my Nova, am going to add them to dads Chevelle and am also going to add them to our 05 Magnum R/T. They do tend to drone a bit but the sound is worth it

Do you mean "louder" or just changing the sound, but not neccessarily louder? If you want louder, I'd suggest some Spin Techs, or bullets. I'm probably gonna be going in the direction of dyno max super turbos, to make it, dare I say it?..quieter? GULP! :D I love my car being loud and just flat out "mean", but I'm gonna be moving in about a month or so, into a back house, and I definatly don't need to be p*ssin off the neighbors at odd hours of the night when going to work tongue.gif :D

well, there are definitely better flowing mufflers out there than the flows, if you're into the chambered style, maybe check out the hooker aerochambers, or ultraflos if you like the turbo-style sound... check out a cross-section view of the mufflers, and you'll see visually how much more flow potential there is vs flowmaster, their respective manufacturers should also have up comparitive flow #s for them as well.... good luck!

checked out hookers site,I like hookers product,just 1 problem,they dont make a muffler with center in /offset out,sept the comp mufflers which I have now--but maybe I can change head pipes graemlins/clonk.gif --I keep lookin--thanks

I tried several mufflers on my 454. All were dual 2.5" with X-pipe. Started with dynomax turbos. Some drone, but not too bad. Sounded a little boring though. Next went with flowmaster delta 50's. Horrible drone. Nice tone. Next walker quietflows. No drone but sounded boring and too quiet. Finally a set of 19" Borla XL. Keeping those. Just a hint of drone at 1200 rpm but easy to live with. Good sound.

How much did those Borlas cost you? I know they can be pretty expensive! :eek:

Yeah, they're proud of them! I think I paid $140 each a few years ago. I just checked summit and they're $168 ea now. They are, however, 100% stainless steel (incl packing material) so they should last pretty much forever. They're also pretty! smile.gif

WOW!!! :eek: That price isn't exactly for the "faint of heart"! :eek: :D

How does it sound? They quiet? They have some "rumble" to them? And what do you mean by drone?

yea ,im lost on the drone thing to,does that mean interior niose level,please explain to us ,please--67rat

Drone = interior resonance. It's when you hit a certain rpm range and the whole interior has this low frequency humming. Decrease or increase rpm and it goes away. To me it sucks. As much as I low the sounds of a V8, that drone gives me a headache.

As for the aound, they are not quiet... but also not loud. A little quieter than dynomax turbos. There is no crackle when you let off the gas like many straight through mufflers have. The borlas are not turbo style even though the shell looks like it. You can look straight through them.

Pretty quiet at idle and cruise, but get louder when you step on it. Also have a smooth sound, not the pop-pop-pop that many other mufflers have.

I would recommend either Walker UltraFlows or Hooker MaximumFlows. Both are a straight-thru, perforated-pipe type construction. Very low restriction, also louder, especially outside, and not much more loud in the inside.

Those come in offset in center out....

I'd really consider if its worth it to get new mufflers. If your engine really needs those massive 2 1/8 headers, heck even if they dont need it, the 2 1/4 pipes will be holding you back. So you'll spend a nice chunk of money for mufflers that are going to be too small if u ever upgrade to an optimal exhaust size. I say save up for a full new exhaust. Even if its 2.5 with 2.25 tailpipes.

As for what muffler, if you want performance, stay away from chambered mufflers like flowmaster.

Those comparisons look good, but then again, that was 10 years ago. Not trying to say those tests/findings aren't valid anymore, I'm just curious as to how those mufflers that were tested back then, test now. I mean, maybe their designs have changed, but they kept the same name/model number? I dunno. But if those numbers/tests still hold true today, then maybe I'll get some Hooker Aero mufflers instead of the super turbos. Something else for me to think about I guess.

Aren't the aerochamber a straight through type design?

I have no idea, I'm just looking for some mufflers that'll quit down my motor, but still give me optimum flow.

Bob, if you don;t want to drop alot of coin, I'd consider a 3" system ready-to-go, or 3" headpipes into 2.5" mufflers. Either wat, you'll very much pick up on the throaty aggressive sound by increasing the headpipe size.

I use the big case Magnaflows, which are pretty quiet. 14-16" cases would be loud. I prefer the straight through design vs the flowmaster. But its just a preference.

If ya wanted it to sound very aggressive, but in a Nascar way, a 3.5" X 3" X pipe off the collectors to 16" case 3" mufflers and dumps would be RIDiCULOUS> plus, it'll sound like you;re winding it to the moon!

Think about much bigger headpipes to get your sound increase.

Merry Christmas!

LXS, it;s really a simple design issue, you need the biggest cases you can fit under the car to keep flow up and dbs down. Using larger pipe dia than required will be louder, so matching the pipe dia to the engine;s output always makes sense.

yea was thinking bout a pypes 3 inch x pipe system,with pro v mufflers,maybe I will go with all new exhaust-I know the 2 1/4 pipe is very restrictive,if I uncork the 427,to open headers,I would gain so much,MAYBE :rolleyes: so I should go with big unrestictive exhaust,probly worth the bucks to let the 427 breathe.--67rat

yea it needs the 2 1/8 hookers ;)

OH YEA ,IM LOOKING FOR SOME HP GAIN ALSO!!

Right now, I've got Hedman headers 1 3/4" primaries with 3" collectors, 2 1/2" exhaust pipes to a muffler shop made x pipe and into a pair of Spin Tech mufflers. It's pretty loud as is, and althought I don't want to, I gotta get some mufflers to quiet her down. So now I'm looking at getting some Dynomax Super Turbos or possibly Hooker Aero Chambers. I'd love to get some Magnaflows because I know those are REALLY quiet, but it'd be cheaper to go with super turbos or aero chambers. I do know Summit has some super turbos of their own, and Enrique (slowpoke) has told me that their super turbo are dynomax mufflers(I think) but with Summit's name on them. I would go that route, BUT I've had some bad experiance already going with "replaced name" parts. I know it's totally different then mufflers, but I had bought a torque converter from PAW, which they told me were brand name converters, like B&M and TCI, just that PAW would put them in a no name box and sell them as their own. Problem was that I went thru 2 of them, then bought an actual B&M converter and haven't had any problems since. Like I said, I know it's totally different to compare, but I feel "safer" spending a little more for the name.

Full Boar mufflers they are stainless steel.......fully welded........very good flow numbers.........and cheap.......

I love my 3" Dynomax Ultraflos

I had an S10 with a 305. It had an LT1 Cam, 2 1/2" Y pipe, 3" intermediate pipe with a Summit Turbo Muffler...... Ended up being too quiet, put a flowmaster on it, and noticed a seat of the pants power increase. And we here flowmasters aren't the best for performance these days.

FWIW

Dyno-Max UltraFlo's with a Dr. Gas X-pipe system. graemlins/thumbsup.gif

GENE,what tailpipes you running,see back in 1990 when I put the exhast on the chevelle I bought a full sysem,jc whitney,I know,but it worked graemlins/sad.gif ,and came with hooker turbos,but it has lots of un-nessesary bends,and to many peices,looking for a system with least bends as can be,but stock exit look,I just like the stock look.a local guy can bend up a 3 inch system and install it,but then someone else will be working on the chevelle,dont like that,wish hooker made full systems,as I like their products,gotta go to 3 inch reducers too!and would like a x-pipe,flow master has 2 peice tailpipes,but I want 1 peice tailpipes.any one make a 3 inch kit other than flowmaster,and pypes?---with x-pipe--also do offset in/center out mufflers work without contacting the south side lift bars?--67rat

GENE,seen the parking lot burn out video here,theres a distinct whirring sound under your hood!!
WOULD THAT BE A TILTED OUT 3 DEUCE L-88 427? smile.gif AT 7 GRAND? :D

OH,THAT SWEET SOUND graemlins/thumbsup.gif 67RAT

need advice on a full kit--please-67rat

If you use Flowmasters kit you MUST use offset/offset to get the system to work. I can tell you that from expierence.

Its all about the 30-series flowmasters. Just buy the american thunder exhuast system, it sound great, even on my little 350.

70 chevelle,its all about 30 series flowmasters?thought of that kit,but would like 3 inch,beings I make power from 4000rpm to 7500rpm,might help with top end exhaust flow,from what im hearing hooker aeros might be the ticket.with an x pipe and tailpipes.might piece together and x pipe,hooker aeros,and tailpipes,NOW I REALLY NEED HELP,IM PICKY ON THIS,DONT WANNA DO IT AGAIN, :( (no yellin,just talkin loud)--67rat

Get some torque tech 3" tails... The largest case 3" Ultra flow muffler you can fit in there and find a muffler shop to fabricate whatever you want in-between.. Be it x pipe.. H pipe...or no crossover at all.

ok thinking this,get some 3inch od header reducers, 3 inch id summit universal x pipe,3 inch hooker aero chambers,offset in/offset out,then take my tailpipes to my local pipe guy and get him to duplicate my 2 1/4 2 piece tailpipes to 3 inch one peice pipes. now can I weld the summit allumimized steel x pipe at the x,dont want clamps there!the alluminum is just a coating ,not?also how far from the header reducers should the x cross section be?--67rat

FWIW...
The local muffler guru was very impressed with the "Out of the box" fit of the torque tech tails.
He had warned me about some other manufactures 3" tails that had used a 2.5" tail to duplicate onto 3" pipe. He had fittment problems with every set he had seen.

hoffbug, do the torque techs have turn down on the end?,or do I gotta clamp some on?,what kind of cash they get per tailpipe?,was on the torque tech site, no info,guess gotta order a catalog,that did cross my mind bout the tails not fitting when duplicated to 3 inch pipes--67rat

ok the torque tech tailpipes are $246 ,think I might get the tailpipes first,hang them,than hang the mufflers,than piece in the x pipe--67rat

Sorry I guess I'm just not with it today

Theres no problem welding aluminized pipe. Its a very thin coating and just burns through.

70 chevelle! I wasnt bustin on ya! :D -67rat

I had the shop put flanges on the front of the mufflers so that the whole X-pipe can be dropped out for transmission work. Ive worked around the pipes in the past and it wasnt any fun ;)

Hey Donny, those clamps are just what I've been lookin for, where can I get them ??? Thanks, Mike

Right-clicking the picture gives a JEGS partnumber of 55530730...

Thank you, Mike

Oh, FWIW I replaced the Flowmaster 40 series with Dynomax Ultraflow on my S-10....noticed a big difference in top end.

Mike you should be able to buy them at any big diesel truck shop.

Donnie

Maybe you could run straight pipe and use Supertrapps to une it to the sound and performance you're looking for. The Supertrap mufflers are installed on a friend's car, sounds good, Tunnelrammed Boss 302 in an tubbed Opel GT shifted at 8K+ rpms and runs 9.60's, so I guess the flow potential is there if enough discs are used. Just an idea.

Junkyard: The 305 went in the s10 because it came out of my Camaro, and the 2.8 in the s10 went belly up. Just used what I had laying around to get the girlfriend back on the road.

Was just sharing my experiance with the SUMMIT turbo muffler.

i once broke in a 383 with a 142 mini blower and we hooked up the flow tech purple honry and everyone was shocked it sounded like a funny car people came from 4 blocks away to see what was up .. it was awsome but extremely loud . imo the flowmaster delta flow race muffler sounds very nice
