I am doing my exhaust on my 86 RX-7 and bought a catback that doesnt fit properly so I was just wondering if I need to buy a header as the stock manifold points towards the ground or if I just need to buy RBs downpipe?

 

Uhh...the manifold has absolutely nothing to do with a catback. The cat is in the same position no matter whether you have a header or the stock manifold..

 

I know but my test pipe doesnt bolt up to the manifold.

 

so it sounds like your test pipe is not correct.

What cat back are you using???

 

A home made one I got for like 50 bucks lol.

 

well there you go...you get what you pay for.

The Racing beat headers, and down pipes are actually bout 1 1/2 inches short of meeting up to to the cat location.

So if you are already short, you would only be even shorter using a RB downpipe or header

 

Really? Time to get the welder out then eh? lol

 

haha did not see that comming

 

Well actually when I bought the car the headerback to the catback was all jerry rigged, and the aftermarket catback is the3 same length as the stock so technically I can use the 'redneck testpipe' that came on it couldnt I?

 

jerry rigged...........more like jerry-RICED!
