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

Thank you, Tony

My bad. Forced Induction was what I was referring to.
F.I Inc . Gotta give it up for their quality and service.

I also have nothing but good things to say about F.I. and Tony. I haven't been able to tot up the funds to purchase the system yet, but when i had some concern regarding a silencer for the system (to lay low from the popos, no need to add unwanted attention with a flashy, noisy car) Tony, chimed in almost immediately and offered me the possibility of a tailored exhaust system for me. To me the prompt reply (customer service), the ravings about gains and quality, the relative price and limitless possibilities with this company really sets it apart from the others.

it seems everyone is leaning more towards F.I because of costumer service and fitment? I have yet seen a dyno comparison stillen vs berk vs F.I.

Anyone here has the Berk CBE? It sounds amazing on youtube, not to mention it looks stock.

Yes but that's only half of the story. Did you read all of the comments? If you did, you'd see mentioning of sound and most important, performance.

Also, if it were just customer service and fitment, it still wouldn't be enough to persway this many people to purchase the exhaust if there wasn't at least a competitive amount gains. So, we know that the F.I. CBE has at least as much gains as its competitors. This puts everyone at the same level. Now, like an interviewer to its interviewees, which candidate stands out the most. Wouldn't the CS and fitment then come into play? I'm not going to mention the manufacturer names cause I don't want to bash or offend anyone, but one had fitment issues from the getgo. The midsection piping was hitting the cross-brase, which required some improvising. Another company also had fitment issues AND packaging issues. Parts arrive damaged OR the wrong parts were sent (two left mid-seciont pipes....or vise-versa). I understand that some of the issues have been address.....but again, during the process of elimination, what would you pick?

Of course, you'd also have to like the look of the F.I. CBE. It's not for everyone, which I understand.

I too would like to see a direct comparison between the CBE systems. Unfortunately, know one really knows what BERK puts down. All of the documented dyno runs have been with HFC included in the equation. Between F.I. and STILLEN, they're pretty close in terms of HP. 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.
