yeah my LM1's are way to loud with long tubes and high flow cats. Don't get me wrong they sound great but I'm getting way to much unwanted attention from the authourities. So I'm looking to trade for a chambered stainless muffler that will swap into my SLP cat back. prefferably magnaflow but will also take mac's. I'm pretty sure both are interchangeable. these would be for an irs cobra. also if someone is interested localy we could swap complete catbacks. PM or email me [email protected]
