Quiet as stock 4x4 exhaust

[Ack-CB11_imp]

Looks great and sounds stock, w/o a converter.
It's from Endurance in Japan :

Not sure but I think duels look better then quad?
I canceled my Two Tails, looking for complete system now.

Is it a weight gain or loss compared to stock?

Back when stock was 4 mufflers, everybody wanted the cool Kerker 4 into 1.

True.., same in the case of the 550, the 550 supersport was exotic with the 4to1 exhaust when it came out than the 550 with four pipes IMHO.. well it all is a personal feeling I guess..

I'll have to stop being lazy and get pics and a video of my Moriwaki one piece up on here. It doesn't sound much different from that endurance system actually.

Man, that 4 into 4 was really puffing smoke after the high revving session

What do they do about the O2 sensor?

Hard to tell from the picures. If it merges after headers before splitting out again it should have a bung there I would think but if it doesn't do that I have no clue.

I just sold my all original 76 550F with the original exhaust and it sounded remarkably like the cb1100 except even more so like a heavy duty sewing machine. Precise and tight.

What a pretty 550F
