    @jonne123 Probably won't be that much in it then over a budget pipe. Usually it's the weight of the stock pipe that does it.

    Bang for buck in my experience, is swapping the ignition system out for a Zeeltronic.

    But I have no experience with the 94 CDI.

    Tuning is an art, and not a single component on its own will make that much of a difference. But getting a collection of supporting mods will.

    What head are you running? The earlier ones ran the restrict 3BN head. And having that changed will make a difference. 3MB heads came factory fitted to the later models, but are getting hard to come across these days. Having the restriction removed would cost less than finding a decent 3MB head. Talking £35 to have the head modified.

      There is a combustion ring on the 3bn head. That needs removing.

              Has anyone found something that is cheaper than the original exhaust rubber?

                  @declan I think I tried that and it didn't work.

                  Honest to God, the exhaust joining rubbers did my nut in on my DT. Glad I don't have that anymore.

                          RE/X are the same. R is slightly different.

                              Yeah, it's the same engine. There are a few mounts that aren't right. And the tail pipe is off every slightly. So needs a joiner.

                              Not particularly worth it IMO. Unless it doesn't cost you anything to make the parts and/or the part you're buying is dirt cheap.

                              So to confirm.

                              • Front mount won't align on the expansion chamber
                              • Middle Mount on expansion chamber won't align
                              • Rear Silencer doesn't align

                                      Or just some brackets. You will have to have a look on this forum where the mismatch is.

                                      I'm pretty sure there is a photo about how far off the end can is.

                                      it's not worth it IMO. Just get a DEP pipe that's fitted to the bikes frame.

                                          I can't help feel like the contours are different. So you still need to mount the silencer in a different location. It's not worth the faff.
