Hi to all can help me ! Im so confused so I got a aftermarket headers collector flange is 2.5 . I need a flange for my back pipe does the size is 2 1/4 the real question is wha size of flange I need to buy ! Thanks for you help !

 

Thanks everybody!!!

 

I don't think your question is very clear. Maybe you will get more replies if you add some more information and some pictures always help!

 

Yea that's what I tough ! But any ways I just figure out ! Thanks

 

just take your header to a ex shop and have them make you a pipe thats 2.5'' on one end and 2.4 on the cat end. if you cant take the car to the shop you need to measure how long you need the pipe to be.
