does any body have any videos or sound clips of a g35 sedan with coupe mid pipe ant test pipes with oem muffler i would like to know what that sounds and if it would even sound any different any help would be apperciated

 

When I had my 350z I put my test pipes on before I got any sort of muffler and the stock muffler with test pipes sounded bad. Very raspy and not great sounding at all. The stock G/Z sound is much cleaner and better sounding IMHO. If you are going to do test pipes I would go ahead and do a full catback exhaust at the same time.

 

i actually have almost the same setup your thinking of except i have berk cats, 06 coupe middy, and 05 oem muffler. Sounds real nice and alot throatier than stock.
