                  @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.
