Well, bad news. Wife hated the drone in the cabin without the muffler so I had to weld it back in. I left the glasspack and the black tips though so now I guess I'll just wait for the fiberglass in the glasspack to melt. I have a feeling I'm just going to end up buying a complete exhaust system in the long run, but fyi... if you put the 25" thrush glasspack and do the muffler delete with the y pipe... it sounds really, really good. All my friends who heard it run before i had the muffler re-installed were pretty upset that I did it but... happy wife happy life! (4th gear had a gnarly drone throughout the cabin)
