Triumph Speed Twin Exhaust upgrade Vance & Hines and X pipe

[@AdamCroll]

Which setup sounds best?! are the V&H silencers worth the money for their good looks?

[@llloralles]

now you should try it without the dbkiller

[@thecomedian4967]

Did you have to get a power commander for the fueling or did the motorcycle ecu adjust the fueling adequately enough?... I have the same setup on my Thrux R.

[@coleythailand999]

I can understand your pleasure at these mods because I did similar on my T120. Vance and Hines plus xpipe. It isn't much louder but the engine does feel more free and it is more fun in low gears in town. Good job for doing it yourself! I am not so patient ha ha. Keep up the good videos.

I would like to inquire about the specifications of the graphite gasket for this exhaust. The tail section of my bike's exhaust pipe is a bit loose

[@midas61]

Great video other than...Why didn't you take the baffles out before you did the X-pipe and again why not do a sound comparison with and without the baffles after you fitted the X-pipe???

[@srhintz]

Hodaka pic for the win! Three suggestions: 1. Condor stand. Roll bike in, pop the back or front end up if need be. No fall, no worries. 2. Loctite 3. Torque wrench. I was cringing when you tightened some of those bolts. A little corrosion and they will snap or be marred trying to take loose. That was a lot of work, thanks for the vid. Sounds bad-ass-tastic!

[@AdamCroll]

A Hodaka Road Toad was my first introduction to two wheels when I was a child! (My Dads)

[@RobertSmith-bh5cv]

In the final comparison starting at 18:45, the stock exhaust clearly sounds deeper and, at least to me, better. The V&H and the V&H + X pipe have a higher pitch and less refined sound. I'm not against performance mods and if the V&H + X pipe gives you a feel, (you claim it has more torque), that's great. But from a sound perspective, at least from the perspective you shot in the video, stock wins IMHO.

[@AdamCroll]

In person it’s better! It’s hard to translate the difference in bass through the microphone to computer speakers or phone 📲 speakers!

[@ianh6943]

Adam Croll I have a similar set up on my Speed Twin. X pipe and V&H silencers. What I have found is the there is a lot popping on a closed throttle. Now I quite like that up to a point but feel it is excessive and somewhat spoils the ride. I have fitted a booster plug but find this makes absolutely no difference. Enjoyed your videos.

@adamcroll I'm curious what's inside the stock exhaust tips? I wonder if you drilled out those rivets could you remove any baffeling or make straight pipes out of them? I have a 2021 speed twin (Not the new 2021), I just got it. I have the xpipe on order. I'm interested in various aftermarket ends, but they're all really pricey. Wondering if you could DIY the stock tips?

[@davidmohr4004]

Hi Stephen...little late to respond but if you haven't got that far...I I have a '22 Speed Twin and actually like the stock sound. I like it even better after I took the baffles out. Super easy job on the US model. Once the the tack weld on the retaining screw was ground off with a dremel, the baffles should slide ride out. Mine were a bit to tight to just slide out but i made a little j hook jig that pulled them right out with out having to pry on them...super easy. I am waiting on a Freespirits XL pipe and want to see how it sounds with the decat and the stock pipes without the baffles. Might be able to keep it less expensive without having to buy pipes if the stockers sound good enough without the baffles.

[@louv3080]

I thought about the V&H slip-ons for my new Speed Twin. Glad I didn't get them as they're too close to the stock cans although I'm sure withOUT the db killers in they'll be much better. I instead ordered the Remus pipes from the Thruxton and hope to have them in a week or 2. Will take the db killers out for sure. Still up in the air about the x-pipe though. Time will tell.

[@hockeymann88]

Great looking bike and seat. I know I'm whining but can't we get Thruxton R forks and shocks on this bike? That would be perfect. Also, sounds great. Worthy upgrade.

It's not live sound I'm hearing but the stock has more low mid frequency & a deeper bark to it which is my preference.

Well done Adam!

[@corvair140]

Great video Adam. Did the same to my T120 including the DNA filter and removing the snorkel. I will doing this to my speed twin too. makes a world of difference. Just remember when all your mods are done to start the engine without touching the throttle and all to idle till the fan kicks in. Triumph dealer told me to do this to reset adaptions.

Great video. Very detailed and clarifying. Thanks for that. Question about something I am experiencing dow here in Rio de Janeiro/Brazil that I would like to know if you have the same perception. So, here is very hot and engine temperature is some kind uncomfortable. So, did you feel any reduction of engine temperature around the legs spot mainly when the radiato´s ventilators are on? (most sensible on traffic jams). Thank you very much

[@javoproject_javoshop]

Hi, Adam. Thanks for share your VDO.

[@mvoutour]

@Adam Croll Hi, Adam, when you installed the X Pipe, did the bike sounds more raspy to you? Almost like an exhaust leak where the X Pipe connects? I felt around and don't seem to feel any exhaust leaks but wanted to see what you experience was when you installed it.

[@AdamCroll]

I wouldn’t describe it as raspy, at least not in an exhaust leak kind of way, I’d say it’s more of a deep visceral bass sound improvement for mine, in my opinion of corse. Everyone’s ears are different though. As long as you can’t find a leak then I guess it’s up to your opinion of the sound, and of corse every slip on exhaust will change it as well.

[@mvoutour]

Adam Croll Ok thanks, I will go and check everything again and make sure I didn’t make any mistakes. The throttle is smoother after the additional of the booster plug and this X Pipe, both of which I did thanks to your videos. SC project exhaust cans are on the way. Thanks for the reply!

nice job, and not too much cussing. I did the same job on a Street Twin, seemed you struggled with different things than I struggled with, but then different bikes.take the baffles out, and hear it roar. Air filter makes little difference, I assume you removed the snorkel? that is a big difference of the two. The adaption just resets the ecu to default, It will adjust by itself over time, just a little more quickly if you run the reset regimen.
