The downpipe is a fairly simple install. I would say it's a 3-4 hour install. High flow cats today are so efficient there is only a 1-2 hp difference and that could just be the difference between dyno pulls.

How hard is it to install down pipe? Any power diff between catted and uncatted?

Thanks.

Hey Rick.. I have a couple question about the tuner and airaid combo. How much does the cai add? Is it worth the extra $200 dollars? And how much boost does the tune add on the 87 and the 93 tunes. Thanks, matt

Rick,

Loving my 2012 FX4 LMS ecoscrew tunes!! What option do I have from you to get tunes for my other 2012 F150, an FX2 ecoscrew? Can I use the same tuner by adding a 2nd license, or do I need an entire tunerr and files from you? THANKS!
