forced induction Turbo Exhaust Muffler Choices / Options

[burndog]

Turbo clan,

 

What mufflers or resonators or combo's are you using in your turbo setup's?  I have to replace mine from the turbo outlet all the way back to the muffler and wanted suggestions, performance first, sound / tone second.  This will be a street car... and smog exempt, no cat needed!

 

Thank you in advance,

I have used Flowmaster HP2 series mufflers on turbo cars (one was a  factory 2002 turbo) and they worked great.  They flow great, sound good, no drone!  They come in Steel and Satinless, they are 12" or 18" long 4" deep and 5.5" wide.  They are available in 2", 2.25", and 2.5" inlet/outlet. They are easy to fabricate an exhaust system with that does not kill your ground clearance.

IT seems from this picture you used two of them???

Yes, you need to run 2 or it will be very "blatty" that is just too long of a run to get away with just one muffler (doesn't really matter what one you use it won't sound very good) this sounds great on the '02 Turbo

I know of two turbo cars here in the Seattle area that use a glass pack as a resonator and a Magnaflow muffler. All custom.

I use a similar setup on my non-turbo car. It just works.

Turbo cars need less muffler than NA cars because the turbo itself acts as a muffler and can cut close to 50% of noise. It's actually pretty awesome that a turbo acts as a muffler, because as we all know, a restrictive exhaust is terrible for a turbo. 

 

If you look at a lot of the super ultra crazy turbo Porsches, many of them don't have mufflers at all thanks to space constraints, and while loud, they are about half as loud as an equivalent length non turbo straight pipe would be.
