WTF does my car have VTEC?

@XSNRGE

Thanks for the response guys! I’ll be PM’ing you in the future when I have some more questions regarding my build!

R33, I believe a 3" exhaust does lose power… I’ve got a 3" Bee*R on my SOHC KA. Only mods other than that are intake pipe and HKS filter. The moment I removed the silencer from my exhaust, I really noticed a loss of low-end torque. The mid-range climb to top-end improved by quite a bit, but it wasn’t too much of a drastic improvement to justify baiting your car with a loud exhaust with only minimalistic gains.

If I could do it all over again, I’d be running a 2.5" high-flow cat and cat-back… As for 2.5" cat-backs, no clue on what to run with, though…

Whats the stock KA downpipe-to-cat diameter?

very well said thats exactly the result u loose lowend torque but gain minimal up top…2.5 inch exhaust have proven to be fine up to 400+ whp
