My setup is 3'' dp and 3''->2.5'' tp with 2.5'' Greddy SP exhaust. My butt-dyno is saying I gained about 30whp but I do have annoying drone at 2300rpm-2900rpm lol. I have to speed up to 75+ mph to quiet down drone. Since exhaust diameter is different which diameter should I use for my setup? 2.5'' or 3''? Based on what I've read 28-30'' capped pipe sounds about right? Thanks in advance! Jorbes13 likes this.
