Gmmg/mad hammer cat back?

I just picked up a 98 z28 and want the same exhaust I had on my 93 z28. Too me this is the best sounding exhaust I've ever heard on a sbc. Does anyone know where I can find it?

Score! That's way less expensive than I was expecting!

The GMMG system on Darren's car sounds amazing.

Agreed. It's what I'd like to replace my broken magnaflow with.

I sure love it. Deep and aggressive even on manifolds and cats.

Even better with headers and OR/Y.

Why thank you!

the best sounding LS car I've ever heard was a cammed GMMG......actually.....that may be the 2nd best now. My bro's supercharged GTO sounds pretty bad ass through 1 7/8" headers and a 3" magnaflow.....sounds like a bomb going off from outside the car when he hits it. Loudest exhaust I've ever heard. If I were doing a catback tomorrow though it would be the madhammer/gmmg exhaust.
