relating to engines to use intake camshaft phasing (cam phasing) to vary intake valve closing (IVC) from normal to early or late closing in order to vary the quantity of intake air admitted to or retained in the cylinders. as in making up for increased flow if thats what you are talking about or if your talking about two seperate headers on one head thats not how its set up its the stock header
V6, V8, V10= two cylinder banks.

hey im gonna toss a cheap thrush turbo under mine next week and turn it out under the door on the passengers side with a nice rectangular tip and call it done. i dont need noise, and im hoping a thrush turbo will still be quiet. but as for someone putting duals on an xj i like the theory but like a couple ppl said, not for me, i wanna know when my axle bottoms/flexs out that theres nothing in the way of it doing so. lol

Give the kid a break, When I was his age I had to have duals on everything - still like'em. And not everyone has a big tool box or fab shop in there back yard...or even know how to properly use a cresent wrench. Labor cost money.

You can buy prebent mandrel bends which are better than the crush bends at an exhaust shop anyway. I built My exhaust out of them

it sounds ok. imo not $350 worth but ok. And as to that "cold air" intake.....the small cone filter you put on there is pulling in some really hot air, it needs to have a heat shield or something.

like I posted earlier 350 = locker, new rims, decent set of used MT's.
In all the rigs I have ever owned.... the most I ever did was swap in a glass pack, and add a turn down after it. the power gains are minimal in a straight six. As for a warm air intake.. all they do is make you use more fuel, cause it makes you think you got more power.
