Single sided exhaust how-to. I figured I would repost this with larger pictures now that I have figured out how to do it...Also since my whole bike is apart for a complete overhaul I don't have nice clean bike right now but I think you will get the general idea by looking at the pics attached.
Being the most recent owner of a heavily abused '00 TLR and seeing how ugly the Yoshi RS-3 stainless exhaust was anyway I sought out sage advice from the all knowing TL gods on how to do a SSE on a TL through the TLZone search function. Thanks to BurnCycle he showed me the way and I now have my own very clean SSE RS-3:thumbup Thanks for everyone’s patience as I am figuring out how to write enough code in order to put this post together:banghead


Take your stock yoshimura header off. It should look like this.


Take a copy of any pictures you can find of how the header pipe needs to be cut in order to make sure the exhaust shop or stainless steel welding specialist knows what you have in mind.




I had them cut off the left side of the header at the point where it is going to give you enough pipe for them to be able to re-use it when the weld to crossover pipe to the right side loop on the header. Have them weld some cross braces on the mid pipe area before they cut it otherwise it will move and the whole deal won't bolt back up together and then you’ll be freakin’ pissed. Once complete it should bolt right together like this.





Total cost - 2 hours of shop time = $120. Having the only a single sided exhaust TLR where I live = priceless.

Looks cool:thumbup

BTW you don't have to type any code, just copy and past the pre-done ones from photobucket - they will be below the pic and start with

Awesome thread, just what the forum needed. The diagrams are very detailed.

I do have a question:how much did all the exhaust work cost you.

Not my cup of tea - 2 cans is part of the character of the TL IMHO - but the write up will be appreciated :) please don't beat on me I couldn't handle it again ;)

Despite not liking the idea :laugh it looks pretty good for SSE ... get one o' them triangular Yosh cans on there :drool or a double sized Aprilla can with the two erm exit pipes

And posxt some pics of the undertail from Chelapa too please :) I'm thinking of doing that too ...

v-twin2001 & Kamikuza

the cut and welding cost me $120 or two hours of a muffler shop's time. Being able to take BurnCycle's picture of a 2 into 1 header to them to show them what I wanted was key - they would have been lost in the sauce without the photo. Went back together super easy and now I can get at my chain to clean it without having to take the right side muffler off.

BTW I had to do this mod anyway or spend $800 on the Ti Force titanium system because my battery side muffler was bent all to hell, so essentially it was a no lose proposition for me. If I had a nice RS-3 system I probably would have been really hesistant to do it. Yeah, now I just need to find a TRS ti Yoshi pipe to really make it nice. Probably won't happen and I will just end up with a Ti RS-3 sleeve and a repack instead.

Just a couple more question. What if any was your losses in HP and Torque? And what does it sound like?

v-twin2001

butt dyno says its the power output is the same but I also changed gearing to a 17/41 520 from a 16/39 530 so who really knows. Haven't ever run baseline HP/TQ numbers so I have no idea. If I had to guess it probably is losing some power because the exhaust is now more restrictive. I won't know until I actually get it on a dyno for a tune once I get a PCIII.

I initially thought it would be alot louder but I think the exhaust pulses into a single can actually are making it a bit quieter. I never measured it before but I think it was actually a little bit louder before with two mufflers and might be a smidgen quieter with only one. I think it sounds great. It's considerably louder than my SV650S with a Yoshi TRS Zyclone pipe, yet it's not obnoxious - I would say it's perfect. Now I just need to get a better looking pipe on the end!

I was told buy the guy I got the TLR from that it was running 120hp on the local dyno. That was with stock headers and RS3 Race bolt on cans and an open airbox (no lid). When I put it on the dyno it with the 2-1, TRS can and sealed/modified airbox can it ran... 120hp :)

The only thing I would have done differently is a scrape and polish job on the headers. :laugh

I may polish out the header yet. I am still trying to get the bike to a point where all of the components are in good running order. Just getting the exhaust finished was a good start (and I suppose only that). I imagine I will eventually end up getting the outside polished and de-burred along with the inside of the pipe which ain't all that pretty either and possibly ceramic coated if I keep the exhaust longterm as a 2-1.

I don't know, that might just be enough reason to do it :laugh
And there was a guy on here selling Ti-force for like $600 :O

Nice job man and great info with the pics, however i would not be to happy about paying for those welds or did the shop do the fab work for that price too.. Have you checked it for leaks?
Anyway its a good mod that is different:thumbup

NSE.ONE & Kamikuza

that price was for fab and weld work. Where I live I am doing good to get this done despite the shoddy welds. The system doesn't leak - which is actually more important than how the welds look - especially since it's a TLR and the header is all covered up by the belly fairing anyway.

I was seriously tempted to get the Ti Force (it got all the way down to $800 shipped), but because I already had an RS-3 on the bike it's tough to throw money at something that isn't broken when the rest of your bike needs so much help. If the Ti Force comes along again though I might have to snatch it up...

fair enough if the fab was involved as well. Just keep an eye on it for leaks especially if ya gunna polish it out as youll be removing even more material.

I appreciate the work that went into it but personally thing it looks funky with only one pipe out the rear. I love the duals
