Rear CAT Delete with RPI?
My coupe runs the RPI rear set up and I don't find it to be too loud. That may be because I don't mind a good sounding if somewhat loud exhaust note (as long as there is little drone in a closed car), or possibly the RPI cans have broken in and gotten a bit quieter than they would have been when first installed (I have heard that this happens - true?).
Apparently the secondary CAT presents significant exhaust back pressure. I had thought of removing it or just gutting it, but wondered if anyone had actual experience with this, using RPI or similarly 'sporty' (i.e. a bit loud) exhaust boxes at the rear?
