bwildman:It had 2 Cat's,,, they gone, and on this you gain 25bhp ( not sure of torque) just by removing these ( hence ask Jules how loud it is LOL its not road legal but who cares LOL). another 20 bhp etc can be gained by fitting equal length exhaust headers as it is a flat four boxer engine. But i like the sound as it is LOL And being turbo'd it doesnt really matter about the lack of back pressure LOL
