I did a search, didn't come up with anything. Is the diameter of the WS 2 1/4"?

On another note, what's the diameter of the stock non-Vtec LS piping? I've heard 1.8"...

The piping diameter of the A'PEXi WS is 60mm, roughly 2.3".

 

i think my WS tip is bigger than that, but maybe not

 

he's talking about the piping, not the tip.

 

i am curious, how does the WS flow vs. say type-r? same for the evo? Like you know people say type-r flows 30% better than GSR. What about the WS and EVO ?

 

The type-r and A'pexi WS both have chambered mufflers. I'd expect the WS to flow slightly better than the ITR. The Greddy Evo, I believe uses a straight through muffler design, which should in theory provide less restriction. I'd bet the differences would be minor however.

 

2.5 on all apexi cat back exhaust

 

I dunno but I didn't think the apexi ws was a chambered muffler. I thougth it was a stright through with a big can to help with the noise.

 

I thought the WS was very quiet?
