ok I have something totally different and very happy with the performance and sound. I went from the cat to a 2inch pipe split to dual dynomax turbo mufflers. Then split to a y pipe staying with 2inch pipe. Then to finish off with 3inch 16 inch long chrome tips. Very low pitch grumble....unless of course you floor it then she gets a little loud. I'm very happy with the dynomax turbo's.;Dr;
