me too i ve had flow masters 40s and i really liked them at idle... now swapped to Dynomax Ultra Flow they sound good at Wot but ad idle they are kind of mellow ;( i asked a friend to drive the car in order to hear them from outside ... i like them a little better ... but still did not find that sound ...

I agree. My Dynomax Ultraflows are way too tame at idle. I miss my flowmasters.

 

Will try and get one up..

 

Its nice when you find it.. Mine is the Dynomax Super Turbo 17749.. I like the tone when new but after 2000 miles they get better and better...

 

I like my 3" exh. with Pypes violators and X pipe from inside the car but can't really tell how they sound outside from idle to WOT...and really can't think of anyone I trust enough to drive the car other than my wife and she wont drive it LOL

 

I had the violators and they were a mean sounding muffler, but just a little too loud at WOT for me. The Borla is a totally different animal...not at loud at WOT...but have plenty with just a sweet tone.

 

Here is a short idle vid

 

Sounds good and nice car!

 

The best sounding mufflers you have never heard of are SpinTech. I have the ProStreet 6000 version. Way, way better than any FlowDisaster offering. Lots of options in size, configuration and sound levels. Plus helpful dimensions, ordering information, videos. Nope, no connection with them. Just a satisfied user.

Had Spintechs on my 72 RS Camaro, agreed they are good.

 

When you open the throttle with XR1s you'll be giggling like a tickled school girl.

 

LOL...Agreed. I was shocked the first time I opened them up..such a sweet sound

 

These are going on my big block El Camino

Gorgeous car. Even better sound.

 

Thank you!!

 

That is a beautiful chevelle, and Im also wondering do you have an H or X pipe ?

 

Beautiful car and sounds good too! Very timely discussion as I have Flowmaster 44's on my car and they are too loud. It is a stock L78 engine with stock manifolds. OK at idle but they drone on the highway and they "rap" on acceleration, like old Thrush bottles from back in the day so I am looking for a change and find Magnaflows pretty quiet.

 

You really need nice headers on an L78. Then mufflers are secondary! Nothing like the sound of solid lifters on a 396. I admit to being biased as that is what I had on my stock L78 ‘67 and you never forget that awesome sound...you hear more engine sound over the sound of the mufflers alone.

 

Thanks guys..I have American Racing Headers longtubes and 3" all the way back.Pypes X pipe and then just installed the Pypes 3" tails when I did the mufflers. Had flowmaster tails but the Pypes look and fit sooooo much better.

 

Pat,

Thanks for the video to be used as a reference.

After you mentioned the Pypes tailpipes fitting better than the Flowmaster tailpipes I looked to see if Pypes sells them separately and couldn't find them. Were you able to buy the tails separately? The way tailpipes fit, in fact, the whole exhaust system is a BIG pet peeve of mine on some of these systems or the way some people install them. My ears perk up when you say, ...the Pypes look and fit sooooo much better. BTW, any comparison pics to illustrate your point?

 

Ha, Morel hydraulic roller lifters sound almost the same! I mean it!

Nice Pat! My buddy Chuck Fame had Borla's on one of his rides and I liked them. Similar to Magnaforw to my ears, maybe a bit better tone.

 

Sounds great Pat!!! I have Borla XS 3" on my car and they sound very similar just not as loud as XR1.

 

Thanks all appreciate the compliments very much

 

Pretty sweet sound.... I've already saved this so I'll be buying these for mine....

 

I am presently restoring a 454 70 Chevy SS. I have a Borla performance exhaust on my C5 2004 Corvette and love the exhaust sound during idle as well as getting into the throttle. Will be putting Borla mufflers on the chevelle build. Nice ride you have there.

 

I second and third the XR 1 mufflers. My goal is a "more quiet than open headered exhaust". I run Vibrant 3.5" x 9" mufflers off the collectors for the track but they set off every car alarm in the neighborhood when I drive in the city. I don't really care to upset the neighbors so I am getting some 3" to the rear axle exhaust done next week with 3" ZR 1's as mufflers. I
won't put an X pipe on there as I want to be able to quickly r&r the exhaust for the track using the Vibrant "collector extensions". Down side is that the exhaust with the Borla's is about + 55lbs over the Vibrant pieces. I do appreciate the Borla XR 1 muffler sound and performance, especially with an X pipe.

 

What is the part number of the borla's you are using? I want to check them out maybe use them next time I need mufflers
