i am plannin to purchase a a'pexi WS catback in the future, but i'm jus wonderin if the WS's b-pipe will be compatible with the stock muffler... cuz sometimes i need to swap them due to personal family issues. will it fit? anyone?

you could save some money and just get a b pipe. With your list of mods, you are going to have a pretty loud setup, I think.

but a'pexi is quiet... but i don't want stock sound, i still wanna show it off a bit but not as far as fart-can. WS muffler doesn't do tat.

the reason i ask for swappin the stock muffler is because sometimes my auntie (the previous) owner comes to my house for vacation and check up on my (her) car... and i don't wanna get her boring lecture, so if i have stock muffler then she won't c anythin.

i see. Well, in that case, I don't really know if they're interchangeable! Sorry!

oOo... anyone else?

The Apexi b-pipe is NOT compatible with the stock muffler. You cannot bolt up the Apexi b-pipe with the stock muffler. The joints are in different places.

If its just a visual thing that you're worried about I'm sure you could get a smaller exhaust tip put on the end of the muffler, if you're more worried about noise and think it will be that big of a problem I'd say you'd be better off with just the b-pipe

the thing is she's only gonna be here like couple days a year, so mind as well run a muffler when she's not here cuz i want deep sound...

i'm still wonderin if a WS b-pipe will fit the stock muffler... anyone?

Happyricefob, since you must've missed this post, I'll repost it. sbslacker said that the apexi b will not fit on the stock muffler.
