Non-noisy 4-1 exhaust system?

I really like the look of 4-1 exhaust, but am wondering if it will increase the sound significantly. I'd like to keep my bike on the quiet side. I especially like the 4-2-1 MAC Honda Tri-Y:https://www.shop.macperformance.com...00-1979-83-TRI-Y-4-2-1-Exhaust-001-0104HP.htm

I'm gradually making some changes on my bike with this as inspiration: https://www.pipeburn.com/home/2016/02/18/1976-honda-cbf550f-by-recast-moto.html

I have a 1980 CB750C.

Can anyone comment about noise level for MAC 4-2-1? (Also performance difference and difficult level of/tips on rejetting the carburetors or other necessary work that would need to be done.) Or an alternative system? Or a specific part I can add to minimize the volume?

no, i recently sold my Seca750 and it sounded really nice. so nice in fact a harley guy commented to me how good it sounded and it ran great. i blew off a new big-inch Superglide with it. you just have to know how to properly rejet the carbs.DSC06453.jpg
