for a civic si 2000 with a b16 engine and few bolt ons and mods. which would you prefer? there a about the same right? performance and sound wise?

 

youtube it.

 

yup Youtube or Streetfire and look for clips of cars with those exhaust on them

 

WS2 is quieter and more stock looking, SP2 sounds a little like the EVO but quieter and is more noticeable in looks.

 

performance wise? with 4-1 headers and 2.5 high flow catalytic converter

 

Tanabe hyper medallion. Its quiet around low rpms so when you are cruising its not loud at all, but when you start getting on it that bitch opens up like a dead hookers legs from atlantic city. Niiicceee as heeelll.

I was in the same situation a while ago. All the WS2's i heard were about as loud as a stock setup and i figured if i wanted it THAT QUIET id just rebuy a stock setup. Tanabe 100%

 

i think they are both about even im asuming they are the same size.
but either are great and are going to sound great,,,
id say flip a coin lol

 

btw its header just to be the grammar ****. Honda's 4 cylinder's only use one header.

 

I just got a ws2 for my eg with a b17 swap. Its quite at low rpms but it sounds great when you really get on it. im very happy with it and it doesnt look like a fart can
