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!

all on the problem side but you have to be happy with a bit louder...

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

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?

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.

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.

I started out with a stock muffler and cat delete pipe with no baffle. I liked it, it seemed to make the RT (a 2015 Limited with 1330 motor) a bit peppier, a little better gas milage, with a little more sound. But that was still a bit quiter than I wanted.. I purchased a custom built SS exhaust from Pit Bull Power Sports for a good bit less than an Ackropovic muffler, now have better performance, and it is not uncommon to get 44 mpg. The sound, well, you decide, here's a little clip with the RPM going over 4,000 rpm.

That's a nice sound; Thanks for posting it!

Hey Bob, I thought this was a newer thread, I think I've posted that video before. I did put a baffle in this one, when You got some RPM's up it had a sharp edge to the sound that got tireing affer a while. I have a good number of folks tell me it really sounds good. To me, it's ok, but depends on the helmet I'm wearing, full face, open face, or half helmet, they all make the muffle sound different. Glad you like it.

So did you do anything else like a K&N and/or power commander? I'm trying to decide if I just need the cat bypass and a different exhaust. I already have the cat bypass, but I haven't installed it yet. I'd rather do everything at one time

I did not do anything other than install a cat delete pipe and do the procedure that recalibrates the computer, and my RT ran very nice. I did the same thing when I replaced the stock system with the exhaust I have on now, shown in an earlier post in a video trying to show the sound of it. I never noticed any actual gains or losses by doing this, but I do have better gas mileage than when it was stock. I can get around 45 mpg if I behave myself, and while I know of no dyno's that will give me a performance graph, seat of the pants says I can hit the rev limiter (8200 rpm) in low and second gear with no drop off in power (IE: it feels very linear ). Some one asked about proper shift points earlier, and that is a difficult question to answer, because it really depends on how you drive, and what you are looking for. I'm used to torquey engines and because of that I tend to short shift (shift early) and my RT seems happy to shift at 2,000 rpm as long as I'm not it a hurry, and I tend to get the 45 mpg number when I don't race around over 3,500 rpm. But my RT with the 1330 engine will shift and cruise, just about anywhere I want to. You can tell if the rpm is too low, because you can feel the vibration or shudder thru the seat of your pants, the rpm too high is almost impossible because of the rev limiter, but red line on the tach is around 7,800 or 8,000 rpm if you go by the change in the thickness of the while line that is on the face of tach showing the rpm. Hope this helps some of you out, or at least gives you another way to look at things. I'm an old guy, and have done a lot of racing ( cars, trucks, go karts and motorcycles,) on road and off, and you can take what if said or not, just enjoy your Spyder, I know I do.

I have a 2016 so I have the 1330.
