You would think. The pipe diameter looks to be the same however i didnt measure it, i just eyeballed it.

I didnt measure the muffler sizes either however they look pretty close too and the hangers on the muffler line right up with where the stock hangers lined up (the rubber bushing didnt change positions)...

Anyway, there must be something different about it because it sounds like it flows much better (it just sounds smoother at idle...the stocker you could almost see each cylinder fire as the exhaust puffed)
