Hi Joel,A fellow GT3 cup car racer got tagged in the rear the other day and it crushed his muffler w/intregal cat. Motorsports wants $4,700 + shipping for the part which seem extreme for a club rceing car. I understand that originally the muffler was spec'd for Supercup. My question is are you aware of any other exhaust system we can use and comply with GTC-3 regs? Can we install straight pipes and if so, would that have an impact on the 02 sensor?Perhaps this should be addressed for a rule change but I believe it's too late for 2008. I thought I'd ask your opinion in the interim...JRG
