I put these on my 2022 Triumph Bonneville. These have a much better sound to them than stock pipes. My Bonneville is a euro spec 5 bike which means the catalytic converter is welded into the system. I didn’t want to buy a new header so I kept it in. With the catalytic converter in the bike, it’s not too loud, but still has great tone. I also bought the optional decibel killer baffles for the pipe after running the bike without them for a couple of weeks. The baffles don’t really lower the sound very much, but I noticed in the lower RPMs the bike seems to run better with them installed.
Another plus is that they are shorter than the stock pipes and you don’t have to remove a muffler to take off the rear wheel.
Another great feature is the weight savings. Something like 9 pounds it takes off the total weight of the bike and I can live with that. This is a good product I recommend it.
