I'm going to get a Hi-Flow CAT as soon as I can afford to, for a few reasons. Possibly a muffler sometime down the road. I have a new OEM muffler and all new pipe now from the CAT back, but it is NOT mandrel bent
How 'important' is it to get mandrel bent if I throw on a Hi-flow CAT and muffler?
If I left the non-mandrel bent pipe on, would I retain some backpressure that I would have otherwise lost, by having pipe that is not hi-flow?
I'd hate to spend more money than I need to, especially since it'* new pipe. If I was trying to make a 12 second car I would change the pipe, but I'm just looking for people'* opinions on the matter. Thanks!
