Wrong cam with the wrong pipe. Sounds like he went for what he could get because of supply problems. I feel his frustration. It's an expensive experiment if the ingredients aren't quite right.
I came across a dealer staged 2 RKS a few months ago that was butter smooth and went like a storm. Pipe was S&S. Can't remember what cam they used but I'm guessing it was SE, given that is was dealer-fitted.

 

@Durham man and @Gimlet
, you're certainly right, I have heard that the 475C is very dificult to tune, and perhaps it's not convenient for his type of riding, but the sound with this cam is amazing...
in any case, while I am a non agressive rider, stages are not my priority at the moment, I need to finalize the configuration of my bike in terms of accessories and comfort...
What I wanted to say is that I love the way my LRS delivers its power and torque, which I find more than sufficient. In fact, I'm a little afraid of losing this pleasure by modifying my engine's parameters...
we'll see later, or not...

 

That’s the conundrum on where you want the upgrades to work. For me I ride mostly 2 lane twisties. Rarely do I get over 4500 rpm. So the Woods 22xe, the new CR 480mt, and S&S465, are on the short list. The RS468 is there as well, but it is a bit finicky to tune if I do the cam myself. Most likely over the winter. Good luck with your choices.

 

thanks for your advice...
I realize that we're now talking more about cams on this topic than about exhausts, which were the original subject, even though they're often related...
and in fact, I'm the one who started this digression, so I'll leave the talking to those who are talking about exhausts, especially as I'm a bit against the grain when it comes to stages...

 

I went with a Thunderheader because I'm nostalgic and have ran them on almost every bike I've owned for the last 20+ years. I like the look, the sound and the power they always seem to make. They're not the flavor of the month stainless pipe that's all the rage lately. They usually fit like **** (although this M8 pipe is a perfect fitment and had zero issues) the coating is crap (near full coverage heat shields on this one, and zero issues) but all that said, at idle and at full tilt boogie, no other pipe sounds as good IMHO. With my Woods 22XD it's rowdy as fvck from idle to 60 days in jail speeds. Bikes getting big cubes this winter so I may have to part with it in the name of power but I'm gonna wait that out as long as possible. A very close 2nd to the T-Header for me are RB Racing pipes but I don't think they make an MB model or at least I've yet to see one.

 

I'd love to have a custom made replica of a high level Thunderheader with Ceracoted muffler but titanium headers so they turn blue in the heat. Would cost silly money though. Maybe one day...

 

I’ll stick with the monthly flavor!

 

George Bryce just doing a Test TI pipe ,David Crane about to tune it in comparison to a Fatcat

 

Done lots of agonising over a pipe choice & gone with the TH, my 1st time love the sound on my 131 custom build nice deep tone without the harsh ness had a Thrashin AR way too loud/obnoxious for me with big baffle!
