Quote from the local exhaust shop to replace the resonator and cut the muffler to straight pipe it was $200 plus tax but includes black powder coated tips to replace the cheap polished ones. 1.5 hours labor with him fabricating a y pipe. He suggested using a magnaflow tube instead of the glasspack but I had already purchased the glasspack. We shall see how his advice pans out next week!
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)
Glad to here you opted for happy life. Would have been cool to get a recording though. I know that annoying resonant frequencies can happen at different RPM and engine loads. Sorry to hear it didn't work out.
