I have the touring. It was stock sounding when I had just the catback. When I added LT and high flow cats it doubled the sound. I can hear it idling and it nice. WOT will let everyone know that your foot is in it. No drone cruising either.

 

I loved the sound of my Corsa sport as just the catback! Just put my lt's and catless y on and love it at idle and cruising but has a god aweful crackle when your in it hard! Will a bullet muffler get rid of the crackle without quieting it down 2 much?
