i'm using a dc ex header on my y7 with a 2.25 exhaust made for my sedan, when i intsall the ex cat will my exhaust be to long, to short, or will it be fine? i've searched and some say it will be fine, and i've heard it will be like a few iches longer?

I'm pretty sure the exhaust will be too long.

Was your origonal cat in the manifold? If it was, then your b-pipe will probably reach the end of the DC header. It sounds like you already have the exhaust on the car. You could go to a muffler shop and have them shorten your b-pipe to fit the cat. Or buy a whole new exhaust for an EX.

 

nothing is installed yet, i have a sedan exhaust from kteller and a dc header for an ex and a cat from kteller that will b relocated under the car, which is 12 inches long, same as ex, or so i was told

 

 

i would check with my local muffler shop (EM)

 

what could they tell me? someone on here must have a similar setup, i just wanna know if i'll have to cut the pipe somewhere or not
