Ok, got a mildly built 350 and have just a set of summit full length headers on it now with just some sections of straight pipe (was just to get it running and driveable for now). well all i can say is that it is loud and my neighbors don't enjoy hearing my car set off every car alarm at 6 in the morning for a 2 block radius when i go to work

i know that I need pipes and exhaust.

on my previous car (69 GTO with a built 389 6pack setup) I was running full length headers and purple horny bolt on down swept glass packs

well i am looking at going back to the purple hornies or a set of cherry bombs that are also bolt on diretly to the headers. but I would like input from folks out there on other options since I have not been in the glasspack or high flow muffler market since the late 90's .

Thanks,

Joe

well the glasspacks would still be very loud first thing in the morning. I fabed up a set with the long tube glasspacks and catalytics for here in Phoenix. talk about annoying, not even a good sound, just loud. can usually find some magnaflows or flowmasters for cheap on craigslist.

And the closer to the header the muffler is the louder it will be. The farther back, the quieter.

 

[UniversalFrost]

luckily, down here in Sierra Vista we don't have the emissions/smog rules you guys in Phoenix and Tucson have to deal with.

only thing is that I will be adding in a cross over tube right after the headers.

I was also considering a set of the thrush welded mufflers

Don't overlook Dynamax Ultra-Flows. Deep throaty sound without the pops of a glasspack.

 

[UniversalFrost]

yeah, looked at price of those ultra-flows and twice as much the cherry bombs, thrush, or purple hornies.

did look at their super turbo's though. my max would be 100 total for both mufflers/glass packs.

A lot of people are saying that the H or X pipes are not quite what they're chalked up to be. If you have a non-restrictive system they are almost pointless. I advise you to stick with glasspacks & turndowns, but make sure they are at least behind your seats.

 

[UniversalFrost]

yes, the purple hornies that have the turn downs will exit behind the front seats.

on my really agresssively built gto they sounded great

was wondering how they will be on my mildly built chevelle

i am really considering buying both the purple hornies and the cherry bombs and do a comparision.

This is my car...355 with 8:1 compression, headers, 2-1/2" pipes with glasspacks and full tails.

 

[UniversalFrost]

which glass packs you have on it?

 

[Highway Star]

Pretty sure they are Thrush glasspacks.

I've had flowmaster 50 series on the truck 3" on a 406 with a nice cam sounds pretty dam good only complaint could be deeper I have 3" on the nova super 40's dumped at tail sounds pretty mean:yes:.. but I loved my dynomax 6" race rounds ..... real raspy sound .....



Back iin the day I've had 3" straights and 3" glasspacks 36 ones. I've had 2 1/2 glass packs cops hear me like 2 blocks away one night ..... too anoying had to go .. lol used to think louder is better . oh i DREADED LONG HIGHWAY RUNS ......

I have installed three W/D/T smooth perforated inner pipe glasspacks on my old '67 1st Gen. car when I had my 11.5 to 1, tripped .060" over, 409 "W" engine in it down each side!

Was still loud, but a lot quieter than w/ nothing on it. Run full tail pipes out the back will help a lot too!

Butt two bodies up tight and weld them together, then continue.. Then add the third one as a resonator out back.
