Do you have the X pipe fitted? Or just the RMB?

Do you have the small resonators?

Hi Don, you may find the RMB with an Xpipe and the smaller rear resonators from MY89 onwards may induce an irritating and annoying drone in the cabin at posted highway speeds. I know! I tried this on my MY89 and within a short 20 minute drive promptly replaced. Am now looking at other options around alternate rear mufflers.

Just RMB, I did this myself and X-Pipe is beyond my capabilities at this time. And honestly I'm happy with RMB only, just wanted a little rumble.

I don't know.

1988 would be large resonators as I recall... Club Sport then GT got the smaller ones first mostly to save weight.
