[alki]

Hey guys
i got a lotus s/s after sales exaust and a janspeed s/s manifold and link pipe!! and it seems loud on full throttle!!....was thinking of bypassing the cat but want to track me lill kitten in better weather....i heard they pretty strict on noise levels on most tracks and even with out the cat-bypass it seems pretty out of order!!, dont wana waste a trip to a track and get kicked off (and i can get a DB meter) so does any1 no the DB limit and at what range??
Thx

depnends on the track...usually varies between 98dB and 105dB at 1m straight back from the car with the engine held at 4000revs ...or something like that ! ...some also do drive by tests
