Noticed you had PRO-fab header for your LML. Would I be out of line to ask what that cost? And one last one did the tune make a huge difference in engine MPG and response vs. stock? I had a 2010 with 5" and the mini maxx and it was like driving a YZ250 dirt bike it had an insane power band not real smooth just crazy power. Wondering if the LML I have now and the H&S delete tuner I just bought will be the same way or smoother.
