I have Corsa and could'nt ask for more ,the sound is just amazing with no drone and for people who say it's ugly , they're probably just jealous because it sound better then anything else , it's not as beautiful as the performance exhaust but at least the tips are not too big and cheesy like a lot of exhausts out there and the cans look badass to me ,at the end ,for the price , it's a f***en deal !!
here's a review by an expert
