Hey guys,

I am look at these BBK headers:

Anyone with a naturally aspirated 4V Cobra, what kind of power gains do you guys see with a tune? Did you install yourselves or have a shop install them?

 

i dont have them on my 4v yet but it woke up my 2v well. can be done at home if u want to save $$$.

 

FYL if you do them at home, i got a shop to install my Flowtechs for $350 bucks, which is superbly cheap since everyone else wanted 700+ to do it.....umm a lot of work required to do it, and MM&FF saw about 13rwhp with a hi flow catted mid pipe...i put mine on recently and she needs a tune, but deff felt it pick up a little...its worth it, but if i were you go on ebay, there are a ton of used sets you can get, i got my flowtechs as a incorrect order, the guy opened th ebox and found out they were the wrong ones, so they wre brand new with all hardware and i got em for 186 bucks...on ebay...so there are deals out there
