Howdy. I have on 05 SRT6 ATM, and I'm debating straight piping it... this has not been a rash decision, no split second nonsense. This has been something I've gone over countless exhausts and through much debate landed with the preferred sound of it Straight piped with the 4 cats... my question is, could this harm the car? Besides the straight pipe drone and slightly decreased fuel mileage I can't think of a way ot could hurt? Also how does this affect the SC with the back pressure?
