Ok so I have 2.5in exhaust all the way back. I found a nice muffler w/tip that has a 2.25 inlet that opens up into a 2.5 main core.
If I get one of those reducers you find at the autoparts store where the reduced section is only like an inch long, am I gonna be creating a noticeable restriction for my car?
I have a Stage 2 COBB AP map flashed to it so im running a little higher boost and a buddy of mine is claiming Ill drop noticeable PSI from that couple inches of the inlet hole + reducer.
Jw if he's gonna be saving me some money or if I know I can make a safe purchase and wont have to go through the hassle of sending things back
