Now, keep in mind I have NOT done a proper search, but is there a straight pipe that replaces the secondary cats? I was unaware that there were two sets. Easy job? I'll do the pulley soon enough, and de-snork or go big air filter, but this cat thing sounds doable!
My new bearings made my car feel slippery as it glides along the road. Just because they don't grind and howl doesn't mean they're not loud or stiff.
