Hey guys, i have a new question. What size of exhaust piping is recommended for better performance in a CIVIC Ex Coupe 94?
1 1/2", 2.00", 2 1/2", 2 1/4".

Thanks! :)

2.25 is the general consensus.. most say 2.5-3 if you're going turbo though

2.25"

5" seems to be working pretty good on my car..........

What is that...the size of the tip? ;) :p

Well, I lied... 5" header-to-resonator, then 4"-to-muffler :rolleyes:

2.25" (2 1/4") should do just fine for you ..I wouldn't go 2.5 or bigger unless you plan to swap and have a 200+ hp motor or Boost your engine.

The larger the tubing, more power will be made at higher RPM at the expense of low/mid RPM. I join the general consensus that 2 1/4" is the most useful choice.

Who needs an exhaust system? Straight down pipe it baby... :devil:

... sparq, you're still talking???
