What I noticed with my APR downpipes.
With the test pipes on I could reach ~100mphs in 3rd gear before reaching the rev limiter, now with the cats back on, 3rd gear maxs at ~90mphs. Didn't realize how much of a difference the testpipes make on the car.

I understand gearing doesn't change but the RPM difference between
the testpipes and cats is noticable. I just switched them out to get a smog check and that is what I noticed.
