    Default New Exhaust for Spysder RT-S

    Hello All,
    I've been fiddling around for the last couple month to come up with a new exhaust for my RT-S. I think i finally got what i've been wanting and looking for. This one sounds great to me, even better as the Two Brother one i had on before. Not to loud but still a good sound and less restricted flow.
    I have been trying out and putting it t the test over the last weeks.
    So far i did not see any issues with it. I did not had to re map the ECU or any back firering issue's. The matter of fact is - since i use pure gas and put the exhaust on my mpg went up. I have couple times now got over
    185 miles to the tank with still 1 gal in the tank.
    Never had that before with my RT.
    The exhaust i have on now (see video) can also be fitted on the RS model.
    I also comes in a less noisier version (sounding more like the Two Brother)
    I'm very pleased. It's about half the price of the Two Brothers or Hindle.
    Let me know what you guy's think.

    That sound...
    So now that you've got our attention; what'll it take to get you to start building them for the rest of us??

    That sounds great to me, could we see a side view. I wonder how restrictive the cat is and what it would sound like without it.

    Default Ho-hum

    Okay ... nice custom home-made rig.

    I want someone to design a better exhaust for the RT line that RETAINS the form factor of the original exhaust, or at least replaces it with something of equal profile. I see alternative exhausts on the RTs ... Micron, Two brothers, etc .... and now they have these tiny little cannisters underneath; the Spyder looks like it's 'missing' something and it's otherwise noisy.

    Maybe I'm a minority. The reason I purchased an RT-S was because I wanted touring/sport touring luxury. I wanted to be able to hear my sound system and GPS, which I can now just fine. It would be nice to have an exhaust that provides more authority at idle and low speed while quietening down once on the roll through 4th and 5th gears (except when goosing, of course). I do long tours in the Summer and to be driving hundreds of miles with that 'drone' of a louder exhaust ever-present is just tiring to me.

    Just my 2 cents.

    Default New Exhaust Road Test

    Here is a video i took yesterday on the road.
    Sorry about the wind noise and my chepper chapper in between.
    I had the microphone attached to my shirt to show how the exhaust sounds and still be able to hear the music

    Nice looking exhaust and it sounds great!
    Glad to know you can still hear the radio while cruising....unlike a typical Harley exhaust system.

    Have you considered re-directing the exhaust to the side or bottom for those that pull the 622 trailer?
    Not sure if the fumes and the added heat would diminish the trailers finish over time.

    You or i can put a different tip on it, like a 45 or even 90 degree and direct it down or side ways. Your preference, i can do it !!

    Just to update you guy's,
    I put over 1000 miles on the RT since i put on the new exhaust.
    Still no problems, even my friends with Harley's say - they can hear me now!!!
    Gas mileage is still in the 35 mile/gal range, loving it.

    Ride safe!

    Default I am interested in buying

    I have a 2010 stock RTS and definitely want to change the exhaust. How much are you asking and what are the installation issues?

    I agree. Sounds nice and looks good. 35 mpg?? I can live with that too. I think a downward angle to the tip would be my preference. Nice job Schultz

    Thanks Bruiser, The Tip i have on was my preference, it can be easly exchanged to a downward angled tip in a matter of seconds. Exspecially for pulling a trailer. The 35 mpg is a combination of "pure" gasoline and exhaust. I'm happy

    First of all sounds great. Loved the video. One of my question is where did you mount the camera, out of all the videos we seen this is the best position to mount the camera. You get to see what is in front of you and there is no vibration in the picture. Second question you said you are getting a 35mpg avg. what were you getting before you changed the exhaust. How difficult to amount the exhaust.? Have you got any pics of the diffferent tips? Thanks JC

    Doc? As loose as the mirrors are on the RT-S, wouldn't there be more vibration in that video if it was under the mirror? (or attached someway to it).

    Hey Guy's
    The camera is mounted via suction cup under the right side mirror on the body panel. I found that as the best place with less vibrations.
    As to the 35 mpg, before i got about 30-32mpg. Every little helps - right?
    The mounting of the exhaust is easy, one clamp on the pipe and one bold underneath the saddlebag. (org. mounting spot)

    Default Quick review of this exhaust

    I purchased this exhaust from Karstens and received it in 3 days.

    I finally got around to putting it on today. Let me start by saying, I had a heck of a time getting off the existing exhaust. There was alot of and alot of that . I am mechanically challenged and lacking all the right tools which adds to the frustration level. That being said, i did eventually get it off without injuring myself or the bike.

    Installing the new pipe was actually fairly easy, but trust me, the was still flying. Slid the pipe over the spyders pipe, tightened the clamp, put the bolt on the hanger(same exact setup as original) and was ready to fire it up.

    The first thing that came to mind once I got off the ground to look at it was, that humungous thing hanging off the side of the bike was gone!! Instant Jenny Craig, i'm guessing around 25 lbs of weight loss?

    OK, was ready to start it up, hoping i tightened everything enough. That will now be my new worry until i take to my mechanic friend and have him check it....

    I fired it up and it sounded just like the video karstens posted, it was awesome. No more sewing machine sounds!! It is also louder than the OEM, I have nothing else to compare it to. It idled very nicely for 10 minutes, revved it a few times and was ready to take it on the road.

    Took it for about 15 minute ride, just waiting for it to fall off or something. At cruising speed I thought the sound was good, louder but still could listen to the radio. When you give it some throttle, it sounds like a beast although nothing like the HD that passed me. The bike also seemed to have some more jump to it esp since I was 2 up. I'll ride later by myself to see how it feels then.

    All, in all, I would say i'm happy with the pipe, the price including shipping was fine, it appears to be made well(welding was fine) but like anything else, time will tell. I like the weight loss for sure, what seems to be snappier takeoffs and if i get a few extra MPG's, that will be good also.

    Karstens!!!

    John

    Oh yeah, If i could install it, anyone can!

    Default quick update

    Put about 60 miles on the bike tonight 1 up.

    1. Def has more power, seems noticeable to me.

    2. Very nice throaty sound at idle and when stopping. Nice!

    3. Loud on the throttle, but to me the engine seems loud also.

    4. At speed i would say its 2x-3x louder than the stock.

    Will check mileage over the next week.
