Hey just got a new RMF narrow header, its 2.5 inch.

RMF Narrow Replica Header B18 by jdmjunkeee, on Flickr

My cat back is 2.36 inch apexi n1

How would i go about mounting them together?>

would I need an adjustable 2.5 test pipe?
someone also said something about a flex pipe welded after the header. Or spring bolts for temporary.
I just want it hooked up for now, enough to get me to the exhaust shop to have a flex pipe installed.

Im pretty confused I don't know much about exhaust fittings. I just want to know if a 2.5 test pipe will fit on that apexi before I order one.

thanks

Find an Omni Power Test pipe, its 2.5 inch diameter. or an ITR cat.

those you can buy with a phalange big enough to accept the donut gasket that comes with the RMF. if not make a custom piece.
