i have an S4 oem exhaust from a nonturbo that i'd like to put on my s5-t because of the rice cannon.

would there be any problems with the exhaust flow?

 

If you're talking about a cat-back system, the non-turbo version is almost exactly the same as the OEM turbo cat-back. I think the mufflers are slightly more restrictive/noise canceling, but the y-pipe should be the same diameter.

 

Thank you so much RotaryRocket88

 

the cats are probably a lot more restrictive than the mufflers, no? especially since they are probably clogged to hell
