I have a hook up with a local distribitor on muflers.
They carry diffrent brands but onlybrand im sure of is magnaflow

www.magnaflow.com

I get close to wholesale cost...and will be cheaper than you walking in any store to buy it...and I got a friend who has an exhast shop that is nto far from Brandon area..that will install it...depending on how much pipe he has to run etc..he charges like 20.$-40$.
