I did nothing to the baffle, but the new tip from DPI (sorry Todd) was quite a bit larger and let the exhaust out faster. No louder that I can tell ,But it sounds alot better for no more then I did. The spark arrester is removed also but if you ride in dry areas a tight screen over exhaust outlet and before tip works.:wave:
I took out the stock spark arrester and small opening tip 1st. The exhaust heated up the plastic tailgate to much for my tastes so I ordered this tip not to increase HP as I am always a sceptic of HP gains until I see a dyno report on said horepower increase. What the tip offered to me was a redirection of exhaust gases and the big plus was a deeper more mellow sound. I have no idea of HP gains because I have no dyno to test on. Sorry if I made it out to be more then it was
