i was just wondering will an axle back off a 99-00 si fit onto my 98 gsr 4dr..becuz i got a mugen tl sitting around

 

Yes, however the length might not be the same. Meaning.....it will bolt up perfectly fine, but the exhaust tip might not sit exactly as it should relative to the end of the bumper.

It might be set in a little too deep or stick out a little too far, I forgot which was which. Just as a reference, my 2 door Integra's axleback fit fine onto my friend's 2 door Civic. It just was a little deep and didn't line up flush with the rear bumper.

 

aite koo...anyone esle got any input

 

are there any differences in 2dr an 4dr axle back

 

just a little bit of lenth, like shamoo said. the bumper is different. the frame is the same for all of these cars, so it will fit fine, but the bodies are different, so the tip might stick out a little too far and look funny or it might be just behind the bumper, which i've heard from an unreliable source can make your trunk stink. for the mugen axleback, though.

 

It will be too short and will not extend out from under the rear bumper cover. You do NOT want this to happen because exhaust gases could find their way into the cabin.

I'm not totally for sure, but you might be able to use the hangers on the twin-loop muffler, and extend the piping to mate up with the b-pipe. However you might have to modify both the pipe and the hangers to get the Mugen tip to extend out from under the bumper cover.
