  • how is the sound from your exhaust ,,, ?

    I have 3 inch cat ,,, 3,5 inch all the way ..farther bak before rear axel ,, big oval muffler ,,, then afer rear axel small round 3,5 inch muffler,,, simons mufflers. But way to loud. Talked with exhaust seller. I have a resonans sound that har super load at 2600 -3400 rpm after that ok. He said that 3,5 inch is to big. The flow at those rpms start doin some flow sounds for my s2 avant. So im going down to 3 inch all the way and putting 1 more big muffler at the end and removing the small one. Im changing to apple dampers ( now hansen racing ) ,, like the sound better ,, simons are to high pitched/loud.
    The best is to put a damper under the front seats a bit after the downpipe , then it will remove the resons sound for shore , but he thinks that it will definetly help to go down to 3 inch and 1 big muffler instead for the small one at the end.

      • Simons mufflers are at best spark restrictors, thy dont really help with keeping sound down. On two of my S2 coupes i have had Dahlbäck racing (it was actually Ferrita that made them then) 3 inch stainless turbo back with no cats (the one in the film, i did weld in a Perrin 200 cel race cat for MOT reasons, its on the car in the clip.) And one muffler at the very rear. You need to use high quality mufflers or you will have loud cars.

              I wonder how big difference it is on stainless pipes and steel pipes actually ?

              I will film my setup now and after.

                  Idle sound , not so much resonating but it should be mounted on softer exhaust mounts.

                    The muffler (actually, the complete exhaustsystem DP and everything) was suplied by Dahlbäck, but they were manufactured by Ferrita. It was part of the tuning kits i had on the cars. The black one had a MTM 340bhp kit and the inka yellow one had a MTM 370bhp kit. The inka one was tuned in 1996 (it was a 1995 S2) and the black (1994 S2) one was tuned in 1998.
