RacersEdge,

In this thread we have been discussing the modification of tail piece / baffles for 97' - newer XR's.

Unfortunately these mod's will not work on your muffler:( .

It looks like Baja Designs has a Thumper Racing insert that will work in your muffler:)

The problem with those is they cost money, and you know how us students feal about money :eek:
I also really don't care if it's louder, just more power! I probably won't do anything since I'll probably be selling it soon anyways in order to get s sport bike.

I drilled the endcap of the sparkaresterscreen with a bit just big enough to pass a punch thru. Then I drove the restrictor out from the back then plugged the drill hole with a rivet.
