So I'm going to order a heartthrob h-pipe or x-pipe, but I'm not sure which one. What do you guys recommend. I'm just looking for a louder sound and the best power increase. Thanks in advance
I was more referring to not much gain from the catback, and that the difference in the X vs. H pipe is minimal and varies from car to car.I'm a newbie when it comes to this. It sounds like Grimace427 is saying an X or H pipe is not going to gain much hp since it's after the cats. How do you get any gains from the X or H, do you install high flow cats?
