i mentioned a few posts back about me getting 98 spec type r headers and a new catalytic converter. i have a 00 civic si with a b16a motor. has few bolt ons and mods (cams, intake, exhaust, throttle body, etc). knowing that the headers have a 2.5 inch collector, would an apexi world sport 2 exhaust be good? its about 2.36 - 2.4 inch piping. not to mention my car is a daily driver. thanks

 

It's about the diameter of stock ITR tubing, IIRC. So you should be more than fine. Most aftermarket civic exhausts are 2.25-2.36''. The larger ones for all motor cars are 2.5''.

I like my WS2 a lot. It's on my EM1. It tucks away really nicely under the bumper so it looks very clean. It sounds almost like stock, but with the windows down you can hear a little bit of it.

I didn't want anything loud or obnoxious. I would chose the WS2 or something like it for a DD.

 

x2!

 

Ya youll be fine, I have a WS2 and a 2.5 inch test pipe and they bolted up just fine. The above comments are dead on, you can hear the motor when you rev and not the exhaust so much, its nice.

 

WS2 ftw! Got it on my EJ1, and it's perfect. No other exhaust for me, ever
I got mine from www.thmotorsports.com they should have the cheapest price.

 

Awesome exhaust, Ive had it on my ej8 for about 2 years now and love it!

 

True, I'm waiting on mines now. I can't wait.

 

what about for flow purposes? gaining or losing power

 

nah if your just using bolt ons its fine. although i got tired of being so quiet after a few months and needed a bit of sound along with my performance. You may want to look for the exhaust sound clip thread or look for vids of your exhaust on Youtube before you decide to make sure you're going to like it.

 

oh ok. as long as im not losing power and gaining then its fine. yeah i heard some on youtube and there a bit quite. but still loud enough to hear. just a tad bit. although some were a bit louder than others. all and all as long as i get some performance out of it. plus its daily car =] and tired of being pulled over because of "modded exhaust" as they say

 

Oh, you can hear it when you step on it.

I loved my ws2.

 

performace will barely be noticed but the WS2 is def. a good pick and sounds good.

friend has one on his s/c gsr and i never notice it will riding

 

X3

wish i could find a used one.... hard to find brother but an amazing exhaust
