Got it done and drove home. The sound is very different. Very mono tone under load. Still has the rasp but more refined. Sounds more like a M3. I think a resonator or two would fix it for sure. Either that or R.T. cats. Will get on it a little tomorrow and see how it feels.
So far nothing has caught fire or melted or fallen off. The fuel mixture is all over the place wrong. To lean almost everywhere except mid-upper throttle in the lower rpm range. Have not really opened it up yet to see what she will do. I switched back to regular gas so I think that I will have enough injector to tune on these for now and switch to bigger next spring for e85.
