What's is the FI exhaust the most popular on this board?

I believe F.I. puts out an average of 1-3 extra HP, which isn't much...so you can say it's identical. I forget the TQ numbers.

A few weeks back 3 of us had the oportunity to run back-to-back dynos. My car runs the Berk Xpipe with stock cats, stock intake, 6MT. 2nd car runs an F.I. 18" CF, stock cats and Injen long-tube intake, 7AT. 3rd car, bone stock, 7AT.

Numbers were as follows (Dyno Dynamics, 61F ambient temp):

FI with Injen LT intakes 291HP
Berk w/stock intakes 288.5HP
Stock 274HP

Seems to me the Berk and FI are putting out the same dyno numbers if you factor in +2.5HP for the Injens

I appreciate that this is not the most scientific comparison, but it is what it is. Being able to have all three pulls on the same dyno within 45 minutes of each other with no real temperature change is a positive.

One week later I pulled on a Mustang and the number was 294HP with the same setup. Mustangs and Dyno Dynamics both tend to run conservative numbers from what I've read here.

I plan on another pull on the Mustang with Stillen G3 intakes installed sometime in the next 2 weeks.

Nicely done!

You really think the Injens are only worth +2.5whp? That's kinda surprising to me that the gain would be so small on those.

As cars have different power levels coming from the factory, its hard to say what their base numbers were without the dyno of it, so the car with the intake could have dynoed less power when stock than Steves so the CAI might have done more for the first car than one might think by just the after dynos. Once Steve does his CAI that will help some but then its a completely different day and temps etc., but should still see. If the gains really are only 2.5 hp then just doing some drop ins would have probably netted the same results for much less money.

I'm not saying anything one way or the other, just reporting the numbers. I'm not getting involved in any pi$$ing matches with the FI people or the Injen people even though we all know Stillen and Berk mods are superior.
