since spark arrestors are a requirement pretty much anywhere you ride, i decided to do a bit of work on mine to keep it legal but flow better.


My muffler uses tuning disks, so i simply used 24 washers to effectively add mucho space for more gases to exit, while using the spark arrestor, can feel the power difference too.

 

Is it just me or does that make it illegal but still makes it look legal? Sparks will get out of those gaps now that they are bigger, those disks are spaced so nothing gets out, if you space them more sparks will somehow find their way out. If you get stopped I'm sure the officer will notice that and ticket you.

 

angry.. good idea.. but probly not legean unless u put in 6 wasers -1 on each bolt them put a few discs.. then so on and w.e.. do you have any pictures
