I've only got a DC cat back, but was reading 103dB on static test at 4500rpm (the track i use has a very understanding tester who never seems to notice i'm not giving him the 5500 he asks for). Not sure what It'd be like on a drive by reading - the bung does make a difference though and drops it by about 5dB, however you also get a knock on impact in performance.

I run 4-2-1 headers/decat and buddyclub pro spec 65 mm. the car is pulling very very good but I can't run this setup on the street anymore cause is far too loud.

.....so for now I put the OEM catback on for now, untul I will modify the oem back box with 65mm internal pipes and some weld job to joint with the buddyclub b-pipe.

....anyway....the car drives like s...et. I loose torque and power. A LOT! the AFR figures are ok, in the range.
On track days I put the buddyclub back on, reset ECU and reload the map. the car is 100% changed :thumbup:


I use the buddyclub only on track for now. In Italy we don't have noise regulations for track days but on the streets the police is hunting us down for every single mod :bad-words:

No I got a decibel meter and tested it at home.... so may not be 100% accurate but it gives you an idea. :)
