MPE + Xpipe
Just had a mastermind xpipe with resonators installed, paired with my existing MPE. I thought the noise would be much much louder. Long before I had a B5 S4 with piggie pipes and a UUC exhaust, it was pretty damn loud.
Does the M3 computer need time to adjust so that the noise will get louder? Also, at the time, the car wasn't at a complete cold start but when I revd the car, it wouldn't let me go over 4k, I had to rev it a few times to get it over 4k, kinda like there was a lag. I thought for a sec that the car was in limp mode but after a few revs it was back to normal.
Any thoughts? thanks
