Selling a pair of SLP Loudmouth I mufflers I purchased for a 2007 Corvette with an SLP loudmouth 2 catback for a direct muffler swap to gain the sound I had originally hoped for in the first place! They are brand new in the box with the SLP factory seal unbroken. These mufflers fit many vehicles and can be turned into a catback system for a fraction of the cost of buying an entire system. Also you can choose the setup (dual single side exit, dual rear exit, both side suicide exit, etc) something you cannot do with a "one size fits all" kit. These mufflers sound great on Ford/Chevy having had them on a Mach1 mustang and a Corvette they give your car an aggressive muscle car tone that is controllable with a loud when you want and quiet when necessary.
