2006 Cadillac CTS, 3.6, Corsa Exhaust, Volant Intake
I couldn't find a good video of this anywhere so here you go. The video makes the Exhaust sound louder inside than it really is but it sounds good. I wanted something that wasn't going to be too noisy inside for long distances but still gave the CTS a distinctive sound. The Corsa Exhaust fits my requirements perfectly.
2011 CTS Coupe with Borla 11824 Axle-Back Exhaust
Finished the install on the axle-back Borla 11824 so here's the before and after comparison. Much meaner with the Borla. I highly recommend it.
