Guys,
I just installed my 4 into 1 exhaust. I was debating whether or not to take out the baffles? It is very quite compared to my old 4 into 2 set-up. I know that I need back pressure to prevent the bike from running rich. Will the baffle grow louder over time as it ages? I really haven’t noticed a power increase over the 4 into 2 set-up, but then again, I only took it for a 10 minute spin and didn’t get it above 5 grand. I need to pull the plugs to see how hot I am running. I was running a tad bit rich with the 4 into 2. I’ll post a picture once my new seat and front brake caliper are installed.
