I have the Borla cat-back system with the tru-bendz test pipe cat delete. I've read several posts on here saying to remove the middle resonator but if you have an aftermaket muffler like the borla one, is it still pretty restrictive compared to cutting it off and putting a straight pipe on? One more question my car is at the shop right now and i was wondering how do you gut the y-pipe and header cats? Is it hard and what tools do you need?
Thanks in advance!
