Putting it on a F3? Looking forward to see what/how you do this and how it looks.
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)

Packaging was nice. Came with all mounting brackets, springs, gaskets clamps, a spring tool and even a center stand stop.

Welds all look nice and for anyone who was questioning it is for sure polished stainless, even the flanges are stainless.

If the weather cooperates will have carbs back on and these mounted up tomorrow, to make a video for those wanting to know how they sound.

Headed to do that after my morning caffeine kicks in. Nothing like relaxing with the family and some coffee on a Sunday morning.

I bought the complete system for about $300.00. Perfect fit, can use the the centre stand, get at the oil filter and it even has a rubber stop for the centre stand.

For the 750? Sounds interesting if you can get to the oil filter and use center stand. Might have to seriously consider this option.

They sell just the header too, Dukie [if you want a diff muffler]  Great price

Small video. Still needs synced, clear tube float heights, tuned and a few minor issues resolved. Rpms hang, which points to vacuum leak, but have all new rubber on both ends of the carbs. Had to bring it back to idle by working the kill switch a few times. And a small drip from #4 overflow.

Did a quick clean with some degreaser but was chasing the sun down and wanted to have some time for pics and a video before it got too dark. Nothing a pressure washing later can't cure.

I absolutely love it myself. I will definitely do another video once i get it dialed in. I'm more up on the 750 and have seen conflicting statements on the 550. Anyone with experience know round about jetting if needed? Plan on a uni filter as well in the stock air box. Carbs are all stock at this point.

It sounds fairly quiet and well baffled, leave your settings stock for the time being, do a plug chop after a couple of days of riding.

No problems at all and the fit is perfect. Its nice and tight still giving plenty of ground clearance but doesn't touch or rub anywhere. I couldn't be happier especially for the price. Didn't weigh it alone but shipping weight was only 17lbs too, compared to the 50ish of the stock setup.

Nice pipe. Looks very much like an old Alphabet header I had on my 550, especially the routing of the head pipes.

Looks very similar other than the collector/mid pipe being separate from the megaphone. Never heard of Alphabet

Your welcome. I wanted let others hear it. I was back and forth deciding on a system i wanted, i really like this one but couldn't find a video anywhere. So i bit the bullet and got it. Will post a better video when i get her tuned, but with a lack of a garage, it might be a few months depending on weather.

Nice fitment and great sound.
Pretty hard to beat on price and quality.
Great to see a few more exhaust options for the 550's.
