    BTW where did you source those exhaust flanges for the cat and downpipe (marco?) and what diameter are they and is a ring gasket available for that size?

      Buddies,

      The Cat is not HKS, but HJS.

      HJS Motorsport

      Best cats money can buy.

        Marco did everything for the downpipe, the ones for the CAT came with the CAT you can order from HJS to what pipe you need the connection.

        Yes the CAT is HJS.

          HJS also sell universal stuff.

          This counts as a flexi pipe?

              Slightly off topic, but does anyone know a source of 76mm (3") race cats?

                  Yes it does.

                  Did You know Audi uses HJS parts in OE installation. E.g. these flex joints...

                  As a matter of fact HJS flex joints are 3-layer ones, unlike the hydraulic store's ones that are usually two layer. Makes them more reliable, still not more expensive...

                    I forgot to add some pictures of the finished product, it took a lot of work and I had to modify the Bn-pipes rear box connections, so I would recommend custom job all the way.

                    Clearence is great BTW.

                    Cheers
                    ps Sorry for the crappy phone pics

                        View from the rear to check the clearence that is very good, well impressed (better than before)

                          Looks very nice, how did you get on over the rear axle?

                            It was supposed to be an of the self system by Bn-pipes but during hardcornering it touched the diff, so it was modify to improve clearences.

                            It is 70mm or 2.75 inches wich is good for clearences, with 3 inches is really tight.

                              Mine does the same. 3" from the downpipe then a slight step down to 2.75" over the axle. Exhaust gasses should have cooled enough at this point anyway
