R33 exhaust system compliance

Recommended Posts

Hi All, 

Can anyone point me in the right direction to an exhaust shop in Sydney that will have an exhaust system available for compliance with the EPA regulations for an R33 Gtst? 

I recently got an EPA notice saying that my exhaust is too loud and I need to have the sound checked to comply with 90db at 4800rpm and ensure it meets emission requirements. I currently know I have a turbo back Xforce exhaust system but it looks like it may not have a catalytic converter due to the previous owner. 

Perhaps a factory r33 exhaust system will do as I'm not wanting to spend exorbitant amounts if I can.

Any exhaust shop should be able to jam a cat back into it, and stuff a drilled plate between two flanges to quieten it down if they think it will be too loud to pass.
