So after talking with a few people that boat on the Grand River I decided to swap out the muffler tips for 4" straight through tips. I noticed after removal that the old tips actually reduced to 3" right away then of course the muffler aspect. With the straight 4" is there any chance to pick up a little hp and speed?
