So i'm seriously considering picking up a NON catted off road x pipe... I have a couple questions though
1) I don't want a CEL. Do i HAVE to have a tune to get rid of it? Or is there some other way?
2) what the power gains look like? 5hp? 10? 15?
3) With stock exhaust other than the x pipe, will it be obnoxiously loud?
I seriously googled this in under 5 seconds....https://www.allfordmustangs.com/forum...rwhp-gain.html
There are a bunch of videos on youtube with sound clips of an offroad x with and w/o resonators. That will give you a sound gauge to go off of. I know you're excited about the possible purchase but, take some time and do a little research in the future.
