Hey everyone so in order to save some money i was thinking about making my own exhaust until i can afford a RB tru dual. do you guys have any clue how much pipe i should order? I'm planning on just using the stock mufflers for now as well

 

This depends on whether you'll be using the stock manifold or a header, and how much of the stock exhaust you'll be retaining. I would recommend at least buying two U bends, and one straight 6' length of pipe. It all depends on the system you are trying to build though.

Edit: Fabricating your own exhaust is an arduous task... You'll need more than just piping.

 

Its a PITA but it CAN be an educational PITA. I'm about to do the same exact thing (obtained a rb rr header), so getting buddy buddy with a welder friend and spending some time measuring it out and mocking it up really helps.
