Is it possible to put an enxhaust from a CRX Si on a HB Si. The reason I ask is that I may sell my CRX to buy a buddy of mines' HB and wouldn't mind keeping my custom Thermal and put it on the HB. He said the exhaust on his (Powercore) is really loud when you hit it.

Any help is welcome.

 

It fits fine from everything I have read and been told, just the hatch is like 3" longer in the mid-pipe.

 

CRX to Hatch: add 7" to mid-pipe (close to resonator)
Hatch to sedan: add 12" to tail pipe (tip)

I'm currently running a sedan exhaust on my CRX that was first installed on my old hatch. IIRC, those are the lengths I had to hack off to make it work. all hangers will line up if you put the splice in the right spot.
