I just ordered my bypass pipe so I'll be watching this!

Lighter, better breathing, sounds good, cooler running. We see no cons, just pro!! Go for it!

What he said.... :agree: - all on the problem side but you have to be happy with a bit louder... :thumbup:

For those that have installed the bypass pipe, who installed the baffle also? Just wondering if it is even needed or what is the benefit of installing the baffle also. Thanks

I would have to say, that the baffle is not needed. While it makes it a bit louder, I thought it was a benefit, as it allowed me to hear the what the engine was doing better. It did lose a little low end power, but made up for it by having more mid-range, which is where most of ride, and it also gave me a couple of more miles per gallon. Either way you go will be beneficial, it is really your choice.

I have the Lamonster bypass, with akrapovic exhaust... it sounds much throatier. I love it

For you, which was which?

Did you lose low end power with or without the baffle? And, did you have more mid-range with or without the baffle? I'm guessing you experimented quite a bit with the baffle both in and out, is that correct?

better low end power with baffle installed

Thanks Marker. Do you have any knowledge of where on RPM scale the cat delete comes in and goes out, with and w/o the baffle? Most of my shift points are at or around 3k, depending on traffic.

Stock, the shift point is around 3000 to 3500.

With a Lamonster bypass pipe, no baffle and stock RT muffler, the bike pulls better and easier to a 4500 rpm shift point.

We have run the bypass pipe without baffle for a long time. The fuel logs indicate a miniscual increase in mpg. However, the bike pulls better into the mid. I was never one to run low 2000 rpm and expect the engine to pull the gear, so, we probably did lose some bottom.

Some of us like the different power output and sound, while others never enjoyed it and removed the bypass pipe.

Thanks PMK!

This is some good information. Not many folks pay that much attention to performance issues. After I install my bypass pipe I suspect I'll be under my spyder more than once removing and replacing the baffle. It's welcome to have a little guidance before I begin the process.

Thanks to all for responding, I did not mention that we have a 2015 RT Limited. That was my concern, how the triple responds to the cat bypass. Thanks

I had the bypass pipe with the baffle running the stock muffler on my '14 RTL. After the install it ran really good without any flat spots in the rpm range. I will say that after running it 9000 miles the bike was a louder than when I first put it on.

Yes, I do not like Cats or Snakes.

My Toyota Tacoma had cats too, but not anymore...

I don't like cats.

That almost sounds like the start of a "Dr. Seuss" story... :clap:

Hey everyone. New spyder Rts owner here. So does anyone have any sound clips of the bypass and stock exhaust? I ran a search but I seem to be coming up empty handed.
Sounds like the bypass is the way to go for sure.

What year is your RT? The sound of the V-twin is totally different than the 1330. I wish I could make my 1330 sound like the v-twin but I can't.

 

[Gallam03]

I have a 2016 so I have the 1330.
