Restored Harley Davidson Golf Cart Loud Muffler


New Member
I all, I have a 1975 Harley Davidson golf cart that I restored and then put 2009 Harley duel 1800cc mufflers on. It is to loud and I'm afraid that when I go to a music festival and drag in at 4 in the morning that I will wake up every one in the camp.
I added 2- 2 1/4 outlets to the stock muffler and then took a short ride up the street. It got so hot it started to warp the stock muffler. I think I need to take out the baffles in the stock muffler but I'm not sure that will correct the problem.

Any suggestions? I'm not sure where to go from here.

Please help,


So are you back to the stock muffler or the dual 1800 mufflers? The stock muffler is about as quiet are you're going to get it and still run good.

Right now I'm running the 09 Harley duel mufflers. After trying the stock muffler in conjunction with the duel Harley mufflers and having the stock muffler actually warp I decided there was to much back pressure causing excessive heat. If I cut the end of the stock muffler out remove the baffles would there still be to much back pressure? I love the sound of the 09 duel mufflers so I'm trying the find the balance between the two. My thought is that if all I run the stock muffler shell it would decrease the back pressure to a level that would be close the the same with the duel 09 mufflers together and still give the throaty sound but much quieter.
What do you think?
