catback system
 

ok i want to get a tanabe catback system with headers, first thing i am confused about is," do i have 2 get speciffic headers that are compatible with my catback" what is the down pipe for ?someone said i should get that but dont know how and for what? and the ctaback system does not include cat. converter, do i have to buy a high flow cat. converter or can i use my oem cat. converter?

RE: catback system
 

1. the header connects to the cat. and most are designed to work with the oem cat. so no, u dont need to worry about buying a header that connects with a catback exhaust.
2. downpipes are for turbos, since ur getting a header, u wont need a down pipe.
3. catback exhaust do not include a cat, but some(like magnaflow) come with a test pipe which replaces the cat, which is illegal in most states.
4. u do not have to but a high flow cat but u will get a tiny bit more power out of one. u can use the oem cat.

^^^You can use the OEM cat IF you can get it off of the rest of the exhaust...depending how old it is it may be rusted on there!

ya...i had to use my test pipe for about a week cuz i couldnt get my stock cat off. ended up torquing the rusted a$$ bolts enough to break them off and used the new bolts.
