Bought my bike 'New' in 2009.
Had, Stage 1 and Reinhardts, installed b/4 I picked the bike up.
Switched to a Heavy Breather, and bought a set of CFR's of evilbay, bout 5,000 miles into the bike.
Stock Headers, CFR's , and Heavy Breather, have been on the bike now for bout 10,000 miles.
I did loose some Bottom End, and I get a slight popcorn affect sound (very fant) on decel.
2009 header pipe has no cat.!
Could use a Tuner/Dyno Tune, I'm sure, but I aint got no DIS-COLORING!!!
Reinhardts were 3-1/2 inch mufflers.
CFR's are 4 inch.
