I just put in an apexi ehaust and 2.75 inch pipping in my 94 integra rs. I really dont feel a difference if anything i feel a bit slower. Is this normal when getting an exhaust or do i just need headers for the exhaust to kick in. Any suggestion would help.

 

I'm assuming you're NA?

Get smaller piping, say... 2.25.

2.75in piping is too big for a pretty much stock Integra.

 

2.75" is large, probably too large. You asked about a header, so you do not have turbo.

 

assuming you're stock. throwing on an exhaust you wont be able to tell a difference except for noise.

 

yeah, thats probably too much exhaust for the car. and like said above, exhaust won't make feel a big difference.

 

You don't understand engine packaging. Read the articles at Team-Integra.net before you spend money making your car slower, hehe.

Right now, your low end power no doubt falls on it's face and your top end is probably nonexistent as well
