So I know i'm probably beating a dead horse, I couldn't find any of the specific info that I was looking for though. From an offroad x to longtubes offroad x, what is the HP gains, roughly maybe 10-15 at most? Is this even worth essentially, car is a daily, and I won't have enough money for boost until the end of college(3-4 more years). I Got a set of SP longtubes off of ebay for 200$, bad thing being I didn't get the mid pipe or connection pipes. I did find a 3 inch ARH x, which I got pretty cheap, and now I just need to come up with a set of legs, or the correct mid. I currently do have a pypes 3 inch x, so my question being am I better off just selling the X and the longtubes, and putting my money towards something like a driveshaft? Or just find a set of legs and run it?
