·I've just fitted an aftermarket exhaust on my E5-- Apex'i N1 cat-back (but no downpipe). No instrumented testing, but my seat-of-the-pants dyno says that the car is even SLOWER now than it was with the stock exhaust. Is this possible? What's going on here?
I did the filter first, and the car felt great. Throttle response seemed to sharpen up a bit. Now that the exhaust is in place, I've lost some low-end torque (more or less expected,) but the car now appears to pull LESS furiously even high-up in the rev-range!
As far as other mods, just have a K and amp;N filter (open type, not drop-in) and boost controller. Am running 1.1bar boost maximum. The cat is still in place, too.
Anyone heard of such a situation?
Thanks!
