yes. yes you are.
Anything electrical I can do, and suspension wise, but internal engine work, or something that requires lifting the car I cant do, like most.

B series (and the VCT AU) have Variable cam timming. Id imagine that having more flow would be more benficial to a car with VCT than with the better backpressure/velocity a la the e and au series, due to the nature of the way it revs and produces power up top.

So yes Ill agree with that.

make sure you get some high flow mufflers

i had a magna flow cats in my xr 6 an it ate the casing in em i had 2 of em i now i have red back and it doing thr proper job

Noticed no one punches out their cats?
When I first got my ute it was one of the first things as it had down 250xxx it looked like a coffee machine filter, Completely choked up. Definitely noticeable when your cat is blocked to free flowing.

I'm going after a pacemaker comp extractor combined with 2 1/2 cat back and j3. Want to run a time before and after to see the difference. Will post here again after 1/4 ET
