Yeah, someone just wanted a little more sound
Yep, sure does look like the holes are where the 4 mounting rivets should be. PO did the same on mine, but I didnt know that they were not supposed to be there. Found out last year when I cracked her open on the 401 and one baffle (left) decided I was being to hard on it and chose to leave me and go visit the 18 wheeler behind me. Fortunatly I dont think it hit him (or if it did he didnt notice because Im still here) and I got home as fast as I could. The right one was stiull in, but it was loose and jiggly, so I pulled it out to save a repeat.
Ended up putting a set of dynas on that sound ..... well .... not sure :-( stator died and I havent had a chance to see how it sounds lol .... sooon ..... very soon
My friend did the same to his fuel injected Suzuki and I was thinking about doing the same to my GL500, did you have to adjust the air mixture any after that?I did similar to mine. Except I drilled between the rivets, just to add some sound. Started with 4 - 3/16" holes in each muffler but ended up with 4 - 5/16" holes. Gives just enough so you can hear the exhaust up to 40-45mph, after that wind noise drowns it out. Had my son do a few take offs and drive byes, and I'm happy with the noise level and tone.
Gotta love free mods.
Nope, but I did lose 2mpg (53 to 51) which maybe from winding the motor out more between gear changes, just to hear the exhaust. LOL Maybe I'll get my 2mpg back once the novelty wears off.?My friend did the same to his fuel injected Suzuki and I was thinking about doing the same to my GL500, did you have to adjust the air mixture any after that?
