Has anyone used GT3 Muffler on 3.6 Conversion here?

If yes, can you send some pics also would like to know which headers you used. Thanks in advanced.

PS: Original GT3 muffler from a GT3.

Anything will fit if your throw money at it. If you just like the look, modify a Dansk or something cheap to dual center outlets. GT3 muffs aren't cheap.

you should call Jeff Gamroth @ Rothsport he has designed a really nice GT3 muffler set up that will fit your 3.6.

I'm looking at this option for my '87 3.6 as well. I've spoken with Jeff Gamroth, he has a bolt on system ready to go (not on his website). Another option I'm looking at is quiet horsepower. Apparently it works very well at keeping the dB's down without robbing any power. Its also a bit lighter than a 997 muffler. Decisions decisions.

FWIW, Jerry Woods and Jae Lee both recommend Quiet Horsepower, they tend to know what they're talking about.

I'm looking for a system that first and foremost doesn't drone, then WOT db's, and finally weight.

Quiet HORSEPOWER

To my knowledge, Steve Weiner at Rennsport in Portland also has a system...header to GT3 center twin exhaust too.
