mugen exhaust


what is the difference between the ek4 and the ek9 one? is it one is 2.25" and other one is 2.5".
by the way, i drive a 2000ej9 with b18c4 in it, so do i need the ek9 one?

I think your motor has 2.25" pipe diameter, but you'll need to check it maybe you have aftermarket exhaust?
 
well if its a standard uk engine itll have the 2.25" size like ek4 but if i were you id upgrade to the 2.5" get a aftermarket header and a de-cat/hi flow cat
 
I was thinking about this, I swapped from a B16A to a civic Type Rx B16B engine, but Im still using my EG6 2" exhaust.

Would it be a performance moving to a 2.5" exhaust?
And will the stock EK9 exhaust fit under my EG6? Is this EK9 stock exhaust 2.5"??
 
I have a twin loop for sale if you are after one. It is for an ek9.
