honestly i'd move up to 2.25 in piping since its going to be crush bent, the net result will be about equal to a 2in mandrel bent. Flowmasters and Hondas do not mix, they always sound bad. pick something else. Add a resonator, a can of black bbq grille paint, and a very small discrete tip to your shopping list and you should be golden. If you're not running a cat, putting it back on will help quiet it down a lot. Best of luck
