This might be stupid to you guys but I gotta ask it cause I dunno. What's the diff between the Y-Pipe and the B-Pipe like, when you get cat back exhaust does that include the B-Pipe or Y-Pipe or whatever someone just explain it all please? Isn't one from the headers to the cat and the other from the cat to the muffler or what?

 

im in a giving mood ..


it goes y pipe - then your cat - then b pipe - then muffler

 

Y-pipe=====Catalytic converter=====B-pipe=====Muffler

A cat-back exhaust replaces the B-pipe and muffler, hence it's called a CAT(alytic converter)-BACK exhaust.

There's not such thing as a stupid question.
