Well I put my SI3 Cam in this past week and posted a vid with the Corsa...I wasn't happy with the Corsa and the Catless sound, so I went back to the Flowmaster Catback and couldn't be happier. I love the sound! Keep in mind I'm still not tuned so you can here the car try to regain idle after a few revs. Tell what you think!
