Bonneville America Forums Forums Technical Forums Exhaust Specialty Spares ESPECIALLY loud!

OK...I went out and pulled one of my pipes and did a comparison:

Baffle - overall pretty equal. The new baffle is a different style which results in a slightly larger opening on the new one but not by much (maybe a 1/8"). New baffle is also slightly shorter BUT again, not by much (maybe 1/2"). Overall length of the baffle pipe is about 12-13". The old one is slightly longer due to the lip. I cant imagine that such a minimal difference would cause such a large gain in volume.

Packing material - mine has about the same as yours did except when I pulled mine out it wasn't all bunched up at the end. I can see it happening over time though. My original baffles, when removed, got all bunched up and made it a bear to remove.

I installed one pipe and started it up and it was slightly louder but again, not by much. Based on hearing your bike there is no way my new pipes would be much louder than my current pipes. As a matter of fact Id still say my new pipes would be quieter that Karens short slash cuts.

The only things I can think of is this:
- theres is problem with your baffles construction. I noticed the new ones look to be hand made vs the old ones that were all one.
- the design of the new baffles is not blocking as much sound. The old baffles do not have that conical shape on the ends. They are more like folded lip that is the same diameter as the baffle pipe.
- you may be leaking exhaust... check your header pipe at the head, check the connection at the bottom of the header and be sure your spares are on so there is no leak.
