      Stock derestricted is a good pipe.

      I went from that to DEP and besides the weight difference, I noticed a good power difference.

                    Yes. What is good budget exhaust and it is worth buying? Power increase?

                            @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.
