Would an CRX Si exhaust fit on an DX model? Because I tryed the muffler and it didn't fit or do I have to change out the hole exhaust?

 

?

 

So nobuddy know this about the exhaust?

 

?

 

so your asking:
will a stock crx si exhaust fit on a dx body?
if so then yes. BUT, keep in mind the dx body on some crx's had a small extention between the down pipe and cat.

but short answer is yes, some mod might be needed

 

keep in mind 88-89 and 90-91 do have different mufflers.
88-89 have threaded ends where you use regular bolts
90-91 use spring style bolts with nuts.

that may be why it didnt fit

 

does this apply to aftermarket exhausts also?

 

Yeah because I try to put the muffler on yesterday and there was no change what so ever for it to fit.
