What exhaust back box is on your CSL?

I've done Bedford maybe a dozen times with OEM exhaust. Never had a problem. Very low static test and never pulled on driveby. Always a few CSLs there and never seen one chucked off. Indeed last month I got black flagged and came in all hey up ready to argue my case thinking it must be noise and they said it was not me but the car behind for drfting and they never have noise issues with CSLs.

Bedford do have a get out clause if the sound meters(5 of them) are triggered. You have to insist it is not you but the group of cars around you and insist they do a driveby test.

I think Ss or Miltek are a bit closer to the limit but OEM should never trip the meters. Woppum got binned with his SS full system last year but I would say 95% CSLs are fine.

By the way I don't know of any uk circuits that don't have drive by meters around the track but Bedfird limits are a bit stricter than most.
