I'd like to try and change the sound of my exhaust a little, some more 'rasp n crackle' would be nice but nothing too silly. I have 6-2 headers with twin 60mm secondaries, then into a 3" full mandrel system with a 14'' resonator that is 3" straight through with a 5"body (pic1) under the gearbox, I then have the Reinhard twin 60mm stainless muffler in the rear (pic2). The centre resonator is straight through and has a double chamber with an open section in the middle.
I was thinking maybe a long hot dog in the centre in the centre might be the way to go, something around 20-24" long? Obviously it needs to be legal and not too loud for the track, currently I feel mine is pretty quiet compared to some, but it's hard to tell with a helmet on
Here's a rough video with the current system, it was done with my old 74degree cam in.
