I have muffler deletes and i want something alittle more louder and efficient. I was wondering if i should run an offroad x and turn the check engine light off but if i change the midpipe ill have to get a tuner to make it run better. What about the prochamber? or if i run hi-flow cats will it still be louder with my muffler deletes?

 

I had SLP LM w/a prochamber and hi-flows welded in. It sounded good but was a little too loud and would get some trumpeting or blaring at mid to part throttle. IMO muffler deletes sound best with the stock catted H and worst with an o/r midpipe. A friend of mine had SLP LM and an o/r x. Sound like a cross between a sewing machine and a crop duster.
