I have been gone a while so sorry for the late response. I believe I was the first to use this muffler and love it. It is not real loud but I think I have the best sounding V6 I have ever heard. It has a deep euopean sound and coundn't be much easier to install. I can't wait to hear it my V8 conversion. You guys will love this muffler! the sound clip doesn't do it justice. Ansa has been making exhausts for Ferarri forever.
