Stainless Exhaust Prices

I have an 01 extended cab, short bed silverado with the 5.3. Have already installed a K&N FIPK and popped the screen from the MAF for a noticable increase in power and mpg. Now I'm looking to start on the exhaust. I'd like to put in a stainless Gibson single or dual sideswept system. I know there are a lot of systems out there but I like the sound of the Gibson. Any ideas on who has the best prices?

You can always look on e-bay, summit racing, jegs, stylin' concepts, or ask your local exhaust shop. I had a single 3" inlet, dual 2.5" outlet flowmaster running straight out the back w/3.5" tips for $250.

Thanks for the info!
