True Classic
This is the first FI X I have owned and I have to admit, the FI seems to function very nice (unlike the 124 spiders which I always removed and added IDFs).
Anyway, I'm sure this has been beaten to death, but would a K&N type filter on the end of the AFM and removal of the cat produce any power improvement? And I don't mean what the Butt dyno says, I mean real actual improvements for normal street driving.
The air filter swap would be easy but the bolt/nuts holding the cat on my exhaust have become one with the car and would be an ugly job.
