I ordered a CB350F exhaust system from Busso on November 5, 2022, and it arrived via DHL on December 18, 2022. I sent them an email a week after placing my order asking when my order would ship and I received a reply within 24 hours that my order would likely ship by the end of the month. I received an email from them on December 5, 2022, stating that my order was being shipped. I received a notice via the Shop app I have on my phone that the shipment was picked up on December 6, 2022. The order was delivered on December 18, 2022, and a signature was required. The parts were well packed and undamaged. I can confirm that meters (and meters) of bubble wrap were used.
I also had difficulty discerning what components needed to be ordered for a complete system. The order I placed was for the following items, as if they were “ala cart”: manifolds (headers), silencers (mufflers), flanges, copper washers (gaskets), bands (clamps for mufflers to header connection) and a universal rubber (stand stop). What I got was all of these items plus an additional 4 bands and 1 universal rubber. It would appear that the bands and rubber are included with the purchase of the silencers. This makes sense but is not clear when view the website without understanding Italian.
I had some questions about the configuration of the short tubes welded to the front ends of the right-side mufflers (they are angled differently from the tubes on the left side mufflers) and received an email reply within about 24 hours. The reply addressed my question and armed with that and a careful review of some photos posted on the Busso Silencers Facebook page I was able to determine that the same right side tube orientation was present on the CB350 example bike they show. As one can see from the images on the Facebook page, the headers will require cutting.
The Busso mounting bracket is located on the lower pipe and is hung from the rear foot peg bolt. The upper pipe is then attached to the lower pipe via a tab with hole on each pipe. The bolt that connects the lower and upper pipes was not included in my order. Truthfully, I wasn't aware that one would be needed and did not look to see if they sell such a bolt. As such I sourced chrome bolts that should work well and look period correct for the bike.
My experience was a good one. I am very pleased with the Busso exhaust pipes and feel that they represent a good value. I also feel that they did a good job with prompt communication and were kind enough to reply in English since I don't speak Italian. Given my experience to date I recommend Busso Silencers to anyone looking for a 4 into 4 replacement exhaust system for your Honda CB350 Four. In full disclosure, I’m not mechanically and am hiring a local shop refurbish my ’74 CB350F, but I think that the installation will be easy, especially for someone with experience.

Brad
