Forgot to mention, the Corsa 14138 Cat Back system for the SRT8's was $1,299.00 at
http://www.streetsideauto.com/ . If you enter coupon code "SSAWINNER09", you get another 10% off, bringing the final price to $1,169.10. They FedEx shipped mine - standard - and the system I ordered last Monday night was on my front steps last Wednesday morning - 36 hours later.
(I've seen this system retail for over $1,700.00 at some "famous" race parts shops.)
Awesome!
