I got a direct fit CarSound cat from Performance Center today and hooked it all up. My car sounds much better now for it being a 305. I am very pleased with this cat and hopefully I shouldn;t have trouble with emissions when I am due up because these Car Sound cats have a good rep. When I took off the cat i couldn't resist to hear my 305 with open headers- I didn't want to put the new one on . Sounded pretty good and was quite loud too. Anyway I am assuming you might want some sound clips but i don't know how to do it Any advice would be appreciated. Thanks
