Can you provide the part number for the Magnaflow muffler you used for the dual setup? And where did you get the X pipe?Originally Posted by SexyG35
I had a muffler shop build me a 2.5 inch tru dual exhaust (magnaflow) with an x-pipe and man does it sound mean. Its not obnoxious or ricy just deep and a little raspy. I kept my stock tips for a sleeper look and at idle you can't even hear it.

save yourselves some money, remove your cats and gut the back half of the catalyst. leave the front (pre-O2) catalyst. now you have homemade hfc that are emissions friendly, not to mention sleeper. stock sound, just louder
