i'm still a noob so no criticizes..
right now i have a d series all stock but i added in a C/B exhaust system to it.
if i was to swap in a B series, do i need to change the C/B or will i be able to still use it..? thanks

 

depends on your HP goals. The most you may have to do is add a piece of pipe to mate the two exhaust, or cut a small piece out.

For the time being it should be fine.

 

yeah i have some goal but just saving up for a swap, so i'm concerned about the cat back system and the catalytic converter. no need to replace those when i do a swap right?

 

bump..

 

you dont need to, u jsut gotta make sure the cat bolts up with the header, and there talking about cuttin things because the muffler might stick out farther then it would with the d series.
