anyone have the corsa extreme exhaust? or any corsa exhaust on their cars? im going to break down and buy of of their axlebacks but cant decide between the corsa extreme or the corsa sport? Ive heard their corsa sport and it is the best sounding exhaust ive heard yet on the s197 (my opinion). my local jegs (which i have buying stuff from) has the corsa sport in stock and they are willing to price match with some compaines online that have better deals. But the extreme will take 7-8 days to come in. Is it worth the extra wait for the extreme than the sport?
