well i have got the bc spec 2 on and im not sure on the size of that but the preasure is really bad

 

2.5 is good


but plz dont encourage replica !

 

do you know what size the bc spec 2 is

 

what exhaust are you running

 

buddy club spec 2 is 2.36. thats what i have on my h22 eg now. i made 194whp with an apexi 2.25" exhaust. im sure the power is very similar with the spec2. i ran a 13.1 at 106 with the spec2. im getting a 3" exhaust soon with a magnaflow 3" muffler and will get it re tuned with that.

 

do you find the spec to has really bad back pressure with the silencer in

 

yea the silencer kills lots of power. I think a test was done on a bolt on ITR and the silencer in the spec2 lost like 20hp. not sure if that was crank or wheel, but the point is it hurts power big time. take it out.

 

3 inch and get a real header
