I've searched forever on both g6performance and here, and I can't seem to find an exhaust solution for my 2006 GTP. I'm not trying to spend $700 on an exhaust, just trying to get some sound and growl out of the car. I was thinking of replacing the res with a magnaflow glasspack and keeping the 2.25" stock piping back to an aftermarket universal muffler. The problem I'm having is finding a muffler that will work with 2.25" inlet into dual outs. I've looked at Magnaflow, Flowmaster, and a couple others and I'm not positive what will work or not. Custom shops around Buffalo aren't any help, either. I was wondering if anyone has some suggestions, using my idea or not, as to what I can order to get a decent set up on my car. Part numbers would be great. Thanks for any help!
