Wins.
Free flowing and quiet.

Has anyone got BC header, decat, spoon b and oem backbox? Be interesting to know how loud on drive by that setup is. I currently have all that but with a BC Spec IV and want to know whether by putting the oem back box back on will help much

Does anyone know the db level of a bc 4 catback? Ive emailed them directly just wondered if anyone knew?

I've got a BC 4 BB with BC racespec header, decat and spoon b and its 96db at 4.5k and 120db drive by :mellow:

Getting the OEM BB re-fitted soon and will do another sound test.

Ive got a DC sports mani, spoon N1 catback and passed the 102db at brands hatch. The guy who did the test told me i was on 101db haha!

BC mani and pro race 5zigen exhaust very quiet will be fine on track....

 

[justinchung87]

Whats the maximum db's roughly for most tracks at the moment??

 

[Stewlark]

Anything from 98 - 105 db depending which track.

Question; anyone know what the dc sports system db output is?
