I am currently running my two stock catts and dual straight pipes, no mufflers, out the rear with 4" tips. I was wondering if I should cut off my catts. THey have been destroyed twice in the last year, since I got my exhaust, and the dealership keeps replacing them but it is getting a little old. I was wondering the advantages to cutting them off. I have heard that you will notice a loss of low end torque, true? Any information would be greatly appreciated. Thanks
