looking at both the standard side mufflers and the Sport Exhaust side mufflers and they look the same besides the fact the second hole is "welded shut" on the standard exhaust.

i've noticed that most people hack the exhaust from inlet to outlet (standard gundo hack)

but if one were to cut that second hole out and utilize that, would it be same as sport exhaust or are the internals different and they are just using the same outer shell to save money?

thank you

 

anyone?

 

I believe so...not 100% though. Would be good to find some take offs at a local dealer is throwing away and cut it open to see.

My GTS came with PSE...I instaled the Sharkwerks rear muffler delete cross over pipes and it sounds really good on the street...still kinda of stock like quiet....at the track I can't hear the engine.

I have a rear exhaust idea and need to find a good clean local muffler fab guy.
