    ABY Cat replacement pipes

    Guys,

    Anyone on here know where I can source some cat replacement pipes for my ABY?

    I have a full miltek on there minus the middle box so was wondering what to expect noise wise? It's got a nice rumble to it as it is with the cats but would removing them result in my rumble turning into a thunder!?!?

    Many thanks,

    Jigs

    Going to get louder! Cat replacememnt pipes seem to be a custom made type thing. Might be as well putting in a few more £ and going for a 3" DP and sports cat :mischeif: Could get a 3" sleeved DP like I used to have, offers some advantages in performance and MOT friendly!

    Otherwise, your local exhaust place will do a pair of pipes for something IIR £100 fitted.

      You'll need the flanges as slot of places don't have them. Kev aka Bambridge on here did mine 6mm S/Steel very nice job. I'm about to get mine done soon ish. Well as soon as GT500 can get me in.
      Just some finishing touches to do now

        Cheers for the replies guys. In a quandry as I like the way it sounds but every speed bump I go over regardless of how careful I am scrape the cats so am thinking od doing away with them.

        Sports cats are an option but I can't justify the cost at the moment and the cats are knackered.

          It is possible to adjust the way the cats "hang" under your car. If you exhaust has not been set up perfectly they cats will hang down too far if out of adjustment.

          The reason I know this, is I have to put mine back on every year for the MOT...

            If your cats are knackered anyway, you may as well gut them!
            Its free and makes a difference

                I bought a set from ebay.de as i wanted to be able to put the cats back in for the MOT. They fit perfectly with the correct flange on either end, didnt make that much difference to noise (rest of exhaust stock), and made a nice difference to performance. Exactly what i wanted

                  If I had the money that's exactly what I'd order!

                    I had the same decat pipes as you. indeed they fit perfect. but i wasn't really satisfied with the bends..
                    i now have the cats back on for mot and than i'm gonna get a 3inch dp remove the y-section and probably add a sports cat.

                      i have a milltek system with the centre box replaced with straight thru pipe, got my de cats from germany, custom made by seller, and a perfect fit

                      the main reason i wanted the cats off was due to banging them on speed bumps and the driveway and even cracking a set on a country road after bottoming out! but the clearance isnt much different with de cats on tbh.

                      the sound, its a bit thundery upto 3000 rpm, over that is fine, saying that, i took the S2 up the M1 the other day, at around the 3 figure mark, my exhaust was popping after lifting off the juicey pedal, didnt see any flames tho.

                      im happy with the exhaust set up tho, but just dont expect to leave the street quitely if u decide to get de cats! lol

                      i personally like the sound it makes, when its warmed up it sounds super, but dont expect much more clearance
