CRF's Only Forums

I am in the market for an A/Mkt. Exhaust System and would like to take advantage of the knowledge this forum can offer. I have a 250CRF,2008 model. Nothing done to increase performance yet. I ride track mostly and would like to get an FMF system. Which FMF exhaust system is the favorite for most track riders that have experience? Is Ti best? Carbon Fiber? Alum. slip-on?

Bottom line-Which one is best/most popular for most advanced riders??


Thanks in advance!

Regardless of exhaust system manufacturer:

1. Carbon fiber or titanium exhaust components do nothing to increase horsepower ... they simply are lighter weight.

2. I've heard many people complain about how carbon fiber and titanium mufflers don't last as long as stainless-steel mufflers and that they are more prone to cracked mounting flanges and such.

3. Titanium exhaust headers are indeed lighter than stainless-steel, but when hot titanium bends/dents much easier than stainless-steel. Many guys report that rocks kicked up off the front tire will dent a hot titanium header.

4. Titanium and carbon fiber cost significantly more than stainless-steel or mild steel exhaust parts.

Working on your riding style will yield much better "performance" than you'll experience as a result of choosing titanium over stainless.

The bottom line is, unless you're a top shelf rider who's looking at every possible way to get a competitive advantage ... simplify and go with stainless-steel parts.
