Running a 3" Downpipe to 2.25" Borla Catback
Do you all see any problems? Or should I be fine ... I konw its quite a bit of a drop off to 2.25" but this is going on an s5 turbo ... not many mods on it.
I thought it would sound great and have enough backpressure .. just gauging opinions

I have that exact setup w/ a bonez high flow cat (from an N/A.. 
) It definatly sounds nice, and is quiet for the most part, but still has a nice sound in the upper rpm's. I have a S5 engine adapted to S4 electronics. Boosts quick and psi goes to 6psi.
I do want to eliminate my cat w/ a 3" borla xr1 muffler, and possibly do some work to make the catback flow abit better. I may just sell it and get a 3" catback somewhere.
