HEADERS:
We are sometimes asked if the X-pipe can be used with Headers. Generally speaking, no. Not without a lot of cutting and custom welding. Headers and a free flow exhaust will yield up to 55 HP, but require a lot more $$ and work to install. The X-pipe is a bolt-in and allows you to keep the rest of your exhaust to save money.
