Hey y'all I was wondering which spirals people had used to quiet down their speed engineering true dual set ups, also where they put them. If anyone has gone this route did they use 3" O.D. spiral(s) (seen some on summit racing site) and just grind them a bit to fit?? Any help or tips would be greatly appreciated.

***Note I have an M6 H/C car and I'm just about to install this exhaust system; is it really that loud to require spirals?? I'm not trying to wake the dead when I leave for work in the morning type thing, right now I have 1 7/8" headers into your typical Texas speed 3" Y pipe. Any advice is appreciated.

Thanks again y'all!!

Not a problem. I recall seeing that post and knew that it was near the end of that long thread.

I have the spirals from summit. I cut one of the spirals off because with three it was too quite. Im running the Texas Speed true duals and they helped a bunch with the drone as well.
