I have the Cobra 2 into 1 in Chrome (#2490) on my bike & have had for 4K miles. Looks good, lighter than stock ,has a good sound although alittle louder than I would perfer when I really NAIL IT. Great sound @ idle. I put it on @ the same time w/a Cobra Fuel controller (92-1770CL) Bike runs better & really feels strong in mid range PULLS HARD. I get alot of compliments on it from other bikers esp HD riders. I lost 1MPG overall but that is probably a comb... of both items & I had to set in rich on Low speed setting screw to get rid of most decel popping, decel popping is more pronounced w/ this exhaust if you don't richen it up. If you want I can sent you picures. The exhaust finish has held up perfect as has the heat shields, it was a perfect bolt on fit & Cobra is to be complimented for the high quality of this exhaust.
