OK, I have my axle back 5Zigen and I just got my DC 4-1 Header which hopefully will be installed this weekend. The question is, I need the mid pipe thats goes between the header and the axle back. How do you guys call this Third Pipe, Catback or what? Also what about the Catalytic Converter? Do you know of any shops that will sell them separetly? Hey I'm confused! Any help will be appreciated.

 

Pretty sure you're talking about the b-pipe, and I think you can get them custom-made at muffler shops. As noded by my use of the words "pretty sure" and "I think," you should get some more opinions

 

the dc 4 to 1 connects to the cat...if its a jdm dc type R header you will need to have a custom flange made up at a muffler shop or a test pipe/2.5 inch cat.

 

Well, seems like you need a b-pipe. The stock one should work and if not then get a shop to make you one.

Header -> Cat -> b-pipe -> axle-back

 

Thanks for the respond!!!!!!!!
