stock 05 wr450 exhaust mod

3 posts in this topic

I just got a new 05 WRF 450, and am wondering what I can do to the stock exhaust. .... i want to get as much juice from it, but still keep it quiet. Can I just remove the inner tube? How is this done, do I grind out the two rivets?? Or do I need to get a new end cap?

by inner tube do you mean the perforated core?

if it is the perf core that you're referring to then i wouldnt pull it out and toos it, but i would change the core to a different ratio of metal to holes. 60/40 Perf core is apparently the go.
