Re: Gutted stock vs tuned
I have run both a gutted stock muffler and a MB Y Crossover on my MB 45, also a set of home made duals. Only difference is the tone of the exhaust. I can still turn the same RPM, and have no noticeable gain or loss of performance. On the gutted and Crossover pipes I had to richen up the mixture on my motors Mikuni to get a better idle at cold start up.
