I already searched on here and found only 2 topics on exhaust power output which don't apply to this. My question is what is the piping diameter for the SP2 for the 06-up Si? Also how much power will it add to the wheels? I checked GReddy's website and they don't have specs for this on there. Thanks.

 

Maybe you should contact greddy and ask them?

 

I can try to do that, but it's the weekend so I figured I would try here.

 

TTT, come on and give me some info!

Minimal. Like any other catback exhaust. You cant feel it.

+1
NA route, without Hondata, its just added noise.

 

Will be adding the Hondata reflash very soon. Hoping for some good gains, have the SP2 on the way now.

 

its all a waste until this supposed I-Pro comes out. Or some other worthy tuning software. There's just no good NA ap out. Its all for looks and sound right now.

 

I don't see how you can say that with the proven power these mods have made with other Si's and especially the RSX-S. And you mean K Pro not I.

Actually, it is most likely going to be called I-Pro. It will be a unique system, designed specifically for the DBW z3 motor.

I believe the SP2 is 60mm all the way through. The gains you will get will be in the midrange, not so much on the top. I installed the EVO II with a CAI and received 10hp gain in the midrange, but only 4hp on the top (to the wheels). (185 to 189), and this was with a CAI installed at the same time.

 

^^very nice...

I'm hoping to get into the 190whp range when I get my exhaust on (I'll be getting the evo2). I've got a fujita SRI already and was dynoed at 181.98 peak while 100% stock...
