  • Supersprint Decat X-Pipe - S50

    I'm selling my Supersprint front exhaust x-pipe.

    This fits all S50 cars.

    Part number 786002.

    Purchased new by myself It was fitted early April and has therefore been on the car roughly 1500 miles/4 months.

    Comes with the appropriate hangar piece as shown in the pictures.

    Some very slight marks to the underside as you might expect.

    Images are of the exhaust as you will receive it.

    £300 + postage
    Collection welcome from the Bradford/Leeds area

        Hi. Couple of questions if you don't mind:

        1. What kind of HP gains can be had with this? I assume it lets the engine breathe easier...
        2. Why are you selling?

          im not sure if they are any different, but might be worth knowing this is for a RHD car (i dont know if this part in LHD/RHD are different? worth checking before considering £300 purchase!)

            Based on everything I can find, the pipe will fit both RHD and LHD cars as well as S52 models. It will not fit S54 cars however.

            Performance wise, these are the dyno numbers from Supersprint:
            OEM
            Claimed data:
            Horsepower 321 Hp at 7400 rev/min
            Torque 350 Nm at 3250 rev/min
            Actual data:
            Horsepower 299.2 Hp at 6760 rev/min
            Torque 330 Nm at 3910 rev/min

            Supersprint:
            - No Kat 786002
            - Rear exhaust Ri. + Le. 786066 + 786086
            Actual data: Horsepower 312.8 Hp at 6670 rev/min
            Torque 348 Nm at 4690 rev/min

            Supersprint:
            - Rear exhaust Ri. + Le. 786066 + 786086
            Actual data: Horsepower 310.0 Hp at 6680 rev/min
            Torque 338.5 Nm at 5830 rev/min

            These show that as well as some more BHP, the main gain of the cat replacement is 10Nm of torque brought in earlier at ~5000rpm

            These results pretty much echo the differences I noticed, the car feels much happier to rev past 4k. There was a slight drop in torque between 2-3k I thought though.

            I am selling due to having fitted a rather loud cat-back exhaust system. The two combined were just too loud considering my car is a daily driver so I have refitted my original cat.

              I'm quite suprised this wont fit the s54? I assume they are different part numbers?

              exactly what i've been looking for as well!! :(

                I was surprised too when checking.

                The back-boxes are identical but the cats are completely different on the two models.

                Gutted they are no good for you!

                  Well mine is an S50B32 so there shouldn't be any problems there (thanks for lookin' out Indy). I will have a "meeting of the minds" with my shop in Dubai and get back to you.

                  If I could only get my hands on some "Cost effective" headers to go along with this.

                    I probably should add that I'm open to sensible offers.

                      One last question, will it pass smog inspection (not sure if you have that there, but here, they stick a sensor in the exhaust and measure)
