What are your thoughts.

I sure miss the sound of my Bassani X and catback of my 99 Cobra.

 

H-pipe. X-pipes sound unnatural on a 1st gen. (Although people do it anyways. )

 

Anywhere I can find a soundbyte? I have Flowmasters and they are almost too loud for me.

What mufflers would be a little mellower at idle and wicked at WOT?

 

I love the classic sound of Thrush Super Turbos with the tips cut off at the rear axle. A buddy of mine has Hooker Aerochambers and says they're mellower at idle but still pretty mean at WOT. On my 67 RS I have a whimpy 2" exhaust and glasspacks. However I'm probably switching to a 2-1/4" system with an H-pipe and Super Turbos or Aerochambers. Heck I might even stay with glasspacks for that classic exhaust sound.

 

this is enough reason for me to do it when i get to that point with my car

heres your horse difference on exhaust hot rod did a comparison couple years ago with a 7o cutlass and a built 455 the dropped the exhaust and dynoed 430 hp open headers then put true duals no h pipe or x pipe and it made 412 tehnthey put and h pipe and mage 419 then did the x pipe and made 428 all using same mufflers and same size pipes

 

Dynomax Ultraflow in the oval sound nice, Magnaflows are the same design. Quieter than Flowmasters, but still has a nice rumble w/out the tinny sound of Flows.

The Superflows are a "turbo" or S shaped design inside. I had some on my 70 before the Ultraflows, man what a difference.

 

Interesting.

 

I have an X pipe with flows and everyone says it sounds great

here's what it sounds like on the dyno

I have a 67 with a set of jet hot headers and a full american thunder flowmaser 2.5 exhaust with a h-pipe sounds sweet at idle and will rock ya with a foot in it!!!!

 

I'm running true dual 2.5" exhaust, cheapy long hooker headers, and dynomax super turbo mufflers. My car is pretty docile idle, but at WOT sounds like a real bad machine.

 

Here is my 69 Camaro idling in my drive way. It was miked standing right behind the car and walking around. 69 Camaro with 94 LT1 383 stroker with Hedman shorty headers and Flowmaster American Thunder exhaust with 2.5 inch pipes and H-Pipe.

H-pipe exhaust note


good luck with your project
