U lose a couple pounds. And the muffler is now sstraight thru. The stock muffler is not straight thru. So with proper jettin. , I suppose it would offer better performance. of course I now recommend just buying a Briggs and Stratton muffler. CheAp
easy

A large diameter muffler causes better performance, and better muffling.
A large diameter exhaust tip cause better performance, but lower sound muffling. The larger the muffler pot diameter, the deeper the sound. The longer the muffler pot, the deeper the sound, but the lower the performance. The longer the exhaust tip, the better the muffling, but the lower the performance. There's a balance there. Best balance would be large dia muffler, large dia tip. Short length muffler and tip.
