I am looking at getting an off road x pipe but was curious if the brand of x pipe makes a big difference performance wise. I have seen some o/r pipes costing 160 and some up to 250. I was thinking being the same design it wouldn't be that big of difference and what is so great about the 250. Thanks.
I hear you get about eight rear horsepower for a cat less x-pipe. I also hear they smell to kingdom come. My dealer told me if I got one he would cancel my car warranty. I hear some shops will not change your oil if you don't have cats.
They do have some right to void your warranty since there are engine sensors after that catalytic converters, and without proper tune your car will not run as well as it should based off of those improper secondary O2 readings.
