will a RB header hook up to an aftermarket cat and hook up to stock exhaust and be fitted nice? i have an sp2 that im either going to get rid of or trade it for something that isnt so wide. i have a posting in the classifieds. if anyone is interested

 

Well, you will need some sort of a midpipe. I have RB catback, had a RB header, and a midpipe, and it didnt fit right. Granted, the midpipe was made to mate up to a corksport catback before. So it seems every application may need a different midpipe made up.

I suppose if you have a RB header to RB catback, the RB midpipe would work perfectly

 

RB just makes all of their headers and downpipes ~3" shorter than stock parts or those sold by other aftermarket vendors. The reason is they expect you to use their extra long presilencer with any of these parts, which sits ~3" closer to the engine than the stock cat does.
