I have a Speed by design Kit, The downpipe is 2.5 I believe. I have a 3 inch over pipe, I have a invidia front pipe which appears to be about 2 inches maybe 2 and a 1/4, and a 3 inch hks catback...That front pipe does anyone think could be hurting me performance wise? Debating on buying a 3 inch front pipe just so everythings the same size.
