      Its worth keeping an eye out for second hand spa's.

      Alex AKA Karbonkid bought a carcass and had it re upholstered DIY.

        Before you go down this route, I would research this a great deal, as I have seen cars fitted with just the cross-over section in a different position that then messes with the back pressure and cause all sorts of weird issues with the VANOS, where the cars lost 30-40bhp in the mid-range due to the VANOS becoming confused and not working properly. There is a big thread about it on the M3forum. A big exhaust manufacturer had to completely redesign their exhaust because of the issues.

          Mine had Silencer's where the cats should be. Due to the class regs I had 2x 100cell cats fitted. That gained me 10bhp :thumbs:

            These cars were gaining a small amount at the top end, but loosing huge amounts in the mid-range, so the power step "felt" good, but the reality was a loss of area under the graph.

              think i have std m3 cats (the 200 cell version) which is why it is so quiet
              now. maybe i'll be ok who knows? I intend to run it with the current cat setup anyway.

              Thanks for the headsup.

                car just got back tonight.

                Initial pic

                can't begin to describe how chuffed i am with the intrax 1k2 suspension. As previously mentioned, I no longer have subframe bushings as the subframe is solidly welded to suspension. This is done in conjunction with welding reinforcement plates to the subframe and repairing a little tear. Forget the resin injections, this is what you want. Too bad I have NO pic.s

                You'll just have to take my word for it.

                The supersprint exhaust i must say sounds just right for me. not too loud but I'll have to test it and report back.
