I can not find anybody who makes exhaust system for this car in stainless steel, called tti no dice, waldrons no dice, magnaflow not available, same with flowmaster. would like to step up to 2.5" with the "x" pipe. any ideas?? i`m a one and done kinda guy i know the aluminized metal will rust, maybe not in my life time but it will rust. if it was 200.00 no biggie but for the money there asking good god should be stainless steel. thanks
