where to buy exhaust

I'm looking to buy an exhaust system and was wondering where the best deals were. I'm looking for an SLP most likely but if I got a good deal on a Borla I'd be really happy. Please no flames for another exhaust topic, I figured any sales would be time-restristed so its useless to search for something similar. Thanks guys

American Performance of Colorado (click the banner at the top) sells the SLP for $379.99, and Partsforyourcar.com (click the banner at the top) sells the Borla both for the GA and the Alero.... the GA Borla and the SLP have dual outlets, and the Borla for the Alero only has outlets on one side. The Alero Borla is $579.99 and the GA borla is $599.
