Slip-on turn down tip recommendations for BW exhaust?

Good question. Going to be watching this. I just got a Bimmerworld race (resonated) and it’s loud AF. I forgot about having something ready for tracks with DB limits.

KenO from M3F gave me a good idea on Facebook. His setup allows him to go from 102dB to 95dB. He attaches a small muffler to the M3’s exhaust tip, and on the other end of the muffler is a turn pipe that has dB killer with packed material in it. I think I’m going to replicate that.

Exhaust elbow that I’ll likely go with: https://www.speedwaymotors.com/Mild-...Inch,9757.html

Edit: I think the length of the flange on the muffler will be a problem. Pretty sure the BW exhaust tip is slanted (can’t confirm bc I don’t have the car with me), so the flange will probably be too short.

Hey guys. I’m looking to drive at Harris Hill soon, which has a 99 dB limit trackside and an 85 dB limit at the property line. With the BW exhaust, I know I’m going to get flagged, so I’m trying to find a slip on turn tip that I can attach when I drive at Harris Hill. All of the tips I find are really long, so I was wondering if any of y’all are running one that is shorter. Or, would you happen to know where I can find one that isn’t like 10” long? Thanks.
