F.I. L.H. Vs. Stillen Headers & cats

LateralG'z · 03-02-2010, 09:43 PM

Does anyone know which would make more power, stillen combo of cats & headers or fast intentions long headers? this would be mated to the same exhaust. I have Saclam exhaust and have decided which way to go? this would be also in conjunction with stillen G3 intakes.

I thought the Stillen headers lost power...

I think the HP stayed the same, but lost torque.
For the price it was not worth it in the end, plus the install price or time.

It really comes down to HFC v. LTH. Both are solid upgrades and add good power, but one might not be legal in your area (LTH have no cats).

Might be worth it if you're going FI due to the increased flow.

They both claim descent HP & Torque gains on there websites but not sure which would be better, plan to autocross the car this summer.

FI, better flow apparently

The difference between them is very small so get the one you like the best. Keep in mind that usually when you start to free up the exhaust too much you can lose power and lean it out too much and will then need a tune to get things right.

hey hope your still lovin that awesome assembly of stainless, i was going to go with the FI LTH - no doubt will be a perfect match. If you springing for the no holds bar then track down the maxim works header and music it will make.

enjoy
