[Nova_Houch7]

hi there, im wandering wat exhaust manifold would be best for my 1.3sr, performance wise!
My car alredy has a custom straight thru infinity exhaust, kent cam, head skimmed ported polished and gas flowed, filter.........(and weber 32/34 is comin soon), so thort id better get a better exhaust manifold too.....
ANY HELP PLZ,
Thanks, Luke

i always thought, and im sure i read somewhere that a 4-2-1 manifold is best for exhaust flow over a 4 branch? i.e. a standard sr part, but thats just my opinion

[Ste L]

yea, the starnd sr/gte 4-2-1 is good for normal driving..

4-1's are good when you spend alot of time high in the rev's.. more the torque higher up the rev range apparently..

someone correct me if i wrong though

[Nova_Houch7]

So are u guys sayin to leave my Standard Manifold on there, as im jus doin normal driving, or shud i go for a 4-1, or a performance 4-2-1?

Yup. I would stay with the standard 4-2-1.

I have a 4-1 fitted on mine, and its really moved the torque further up the rev range. Not much use with a 6200rpm rev limit.

yer iv got a 4-1, i think its well good. but then again we all got different styles in driving etc.

[Nova_Houch7]

So wat 4-1 exhausts are about at the moment, that wud fit the 1.3sr, plus add lil mor power?

a regal 4-2-1 would be better but then its not really worth the ?220+ when you can do better mods for the same price.
