2.5" will make the car lose power in the lower RPM range.

will it be bad.. my girlfriend will be driving and shes got the feather foot compaired to my boat anchor.. but other than loosing a little power it will run fine get her to the store,take the baby somewere come visit me in the pokey

[JoshM]

Yes, it'll still be drivable.
She/You won't have anything to worry about.


There are plenty of people on here with 2.5" exhaust on their F-series.

2.5" is too big IMO.

did you not read my shit.. im goin to jail friday and i dont have the time to hunt down the 2 1/4 2.5 is all i had at work so i bent it and brought it home

[v-dub]

but now im thinking all those bends just might help a little its not kinked or anything and its got a good silencer i put on so maybe it wont be as bad

I Got 2.5 On My F22a1 And It Feels Good 2 Me And Np Problems

[v-dub]

word up dude as long as im not over doing it like 3 inch and shit should be fine.. man i need a turbo son!!!!!

Its a trade off 2 1/4 youll gain downlow but lose uptop. With a 2.5 youll lose downlow which hondas really dont have all that much and gain more up-top.

As soon as you put a stage 2 or 3 bisi cam in the f22a though, you'll be close enough to the H22's power that the 2.5" shouldn't hurt you much in any range really. The stock f22, or one with bolt-ons just doesn't move enough air.

I assume you mean a bisi stage 2 or 3 cam with supporting modifications. The jump from a stock 105 whp F22aX to a stock 165 whp H22a isn't quite as easily done as slapping a new bump-stick in.


Regardless, 2.5" will be fine. The only thing I'd be vaguely worried about would be the noise level. And as that's really just a creature comfort, so you'll be fine either way.

Of course the supporting things too. I didn't bother to say it because who's going to do it backwards?

[fatboy1185]

it will be fine dude. exhaust size is the least of your worries at this point in time

[newyorkcb7ss]

Very true. Cant dyno it and tell for sure but my i gained low end a bit. Everybody who drove it before and after i got the 2.5 can feel the torque more in the lower end now! maybe i got freak pipe. Its loud as hell though but that may be due to my lack of a resonator and my magnaflow muffler lol. I got 2 tickets to prove it lol. Getting it fixed tommorrow hopefully!
