I have a 92 hatch d16 sohc non vtec, it has a header, high flow cat, and full Magnaflow exhaust, right now I would guess that it has very little backpressure. Someone told me that Honda's need alot of backpressure, if I were to downgrade my exhaust, say I were to put a stock cat, or if I were to put a stock muffler on it would I see any HP gain? I have decent acceleration, but my top end seems to be lacking power.

 

You'll see more power if you put ALL your stock equipment back on.

 

I almost forgot to ask, are there any tests I can run, or have done to it, to optimize my backpressure, for the my best HP numbers?

 

i bought the car with these mods already on it, the exhaust cost like $300, can I only change one part?

Yeah... A dyno.

 

backpressure will help you off the line. On the top end you should actually see an INCREASE in power.

 

Theres plenty information over this in the archives, this is a thread I found.

what if. . say he got a b16 would he still be losing power? like a 2.25" exhaust?
