Any dyno results? The stock piece isn't that restrictive. Its not exactly laminar flow, but its not catastrophic either. $260 for two 90 degree elbows seems a bit much IMO.

well impouse the one i have, the end is rolled.

tate.. i dont have dyno results because going anywhere from where i live is too far to do. But i do really test every part i get on a straight piece of road from a dead stop, from a roll, and on long drives to my college which take over an hour each way. As for the cost like i said i only paid 160(not 260) for it which to me is worth the cost for the gains i already explained to you, because it does the same job as a CFM+ just for less.

I never had the stock one so I dont have any dyno comparison. But Like 97 D-Tec said they are less than all the other ones on the market and do just as good of job. And every little bit of more air flow hellps with power & EGTs. It may not be a huge gain or drop but every little bit helps. BTW my buddy just put the AF1 pice on his 07 and he said he could tell a diffrence.

The 3rd gen will see a bigger gain than the earlier trucks as their manifold is an inferier design.I am going to go out on a limb here and say the 2nd gens will not see a verifiable hp increase after doing some testing on my own.
