so you're saying by welding on the lunchbox resonator...you got MORE performance than you did with the MBRP itself? and it was noticable? ha. ill believe it when i see the dyno.

<font size="2" face="Verdana, Arial">once again i agree with drew. this loss of torque is due to the kamikazi, not the MBRP. while the noise is due to the design of the exhaust, the torque is not. i have the MBRP on my car and i only felt an overall power increase up top, no torque loss at all.Originally posted by focusownerskid:
The low end torque loss you are describing is the cause of the HUGE Kamikaze 4-1 header.
The collector is 2.5in, correct?
And the primaries are also fairly large and close to the collector, right?
The header is overkill for an engine that is close to stock, if you were to replace that with a FocusSport(4-1, smaller primaries and collector is proper position) or even a Focus Central(4-2-1, smaller tubing) - You would have gotten that Torque back that you lost.
And as opposed to really messing up your high quality MBRP, you could have welded in a single 28in Magnaflow resonator that would have more than taken away your droning problem, and still left you with the performance you desire.
I still can't believe you hacked up a gorgeous system like the MBRP to put the stock muffler and the ass ugly and restrictive box in the rear!

when i pass the other cars, they are question themselves, what kind of car is that? oh it is a focus, a quick car.
<font size="2" face="Verdana, Arial">ditto...no way in hell the "hybrid" setup makes more power. I'm not saying there are huge gains to be made with any 2-1/4" exhaust, but with a CAI and header, you wouldn't lose power.Originally posted by FocusOnPunk:

<font size="2" face="Verdana, Arial">the MBRP comes in both 2 1/4" and 2 1/2" sizes. it's pretty much the general consensus that a 2 1/4" ehaust is the best for an na (normally aspirated, no turbo nitrous etc.) over a larger 2 1/2" wich will loose some bottom end.Originally posted by BerinG:
How big is the MBRP exhaust?
Just wondering, would a Borla exhaust (2.5") give any gains on a stock zetec with cai?
