Dueller 2-2 BIG BORE Sound Test - Street Twin, Street Cup, T100, T120

[@jjnewman65]

They all sound wicked George 👏👍👏

[@movem1]

Enjoyed that immensely, nice options 👍

[@tinks43]

Looking great, Loud baffles sound best to me 👍🏻

[@vitessetortoise3950]

Fitting video to follow?

[@dustytriumph]

I really like the look and sound of these. Too bad I have the Euro5 CAT with welded on exhaust headers.

[@quacktac]

These sound fantastic. I prefer the slash cut look of Motone's exhausts but they're twice the price!

[@davekennedy9060]

Have you considered producing a 2-2 downpipe only system similar to the Baak system for air-cooled Bonnevilles? I'd love a set but the Baak system is so expensive. Great stuff as normal, cheers Dave.

[@TECBikeParts]

Everything from them is overpriced !

[@alexgarvey-welch.748]

Very nice looking bit of kit.

[@armedferret]

Greetings! Will these be available in stock again in the next few months by chance? Particularly on the US site? Thank you!

[@villainvest]

Hi, do you have a video fitting the big bore pipes to the 1200 Thruxton R or similar model

[@grenvillemoore2346]

George, I have a 2016 Thruxton 900 efi Does the Dueller system fit? I want to swap out the stock system for better sound and performance. Secondly, I am guessing there would be no need for an X-pipe with the Dueller system?….

[@Dispariabooks]

Any idea on the DB levels for the various options? I love the sound, but as a daily I don't want it to be as loud as my race bike ;)

[@jakubstoj8118]

Cold you make black siliencers for T100/T120 Black, with some nice shape only those parts missing in your ofert. GJ 🙂

[@motoblueprintguy9097]

Would also love this for my T120 Ace.

[@brettdeiter6464]

So I have a 2020 so I need to remove the cat?

[@spudders]

Nice, like the different baffle options. Will the bike need any tuning or will it sort itself out? Any issues with warning lights on a 2019/2020 Street Twin with the cat being disconnected?

[@georgemilburn6213]

Fine with stock ECU, just let it auto adjust

[@eddiedoran4680]

If the engine management light comes on start running on the more expensive petrol and it will go out after a couple of fill ups.

[@jjnewman65]

Superb!

[@melbinthomas1659]

Hi there team tec bike parts , pls do a video on the oilpump n oilcirculation of 900 bonnie engines!! Best wishes!!!

[@darrylpuah]

if i order the Dueller means i no longer need to upgrade the cat with X-Pipe right?

[@patthewoodboy]

yep , cat can stay in place and fit the Dueller system.

[@utharaptortrex]

What handlebars are you using on this bike? Can't find them in the website.

[@zudeck]

I have the same question as well

[@TheSpagEddie]

What pieces did you use to be able to use the rear stand?

[@leehodgkiss15]

I have a 19 plate street Twin which stock is around 60 bhp, what performance improvements would I see if I installed the full system with a performance air filter? Would it get close to 70bhp?

[@1ridgy]

Looks great and sounds bl@@dy fantastic. Do you intend to fabricate / produce a full 3/1 system for the Trident 660?

[@TECBikeParts]

sure do !

[@1ridgy]

@@TECBikeParts keep me updated please

[@graytester4089]

Hi. Does it need tuning after install?

[@brucesherborne408]

Can you do a vid on the 2 into 1 system

[@georgemilburn6213]

we have one plus several others on the 2-1 here- kzbin.info?search_query=tec+rebel+2

[@leehodgkiss15]

What are performance differences on a street Twin?

[@patthewoodboy]

from what I've seen , George says the Cam is the restriction on bhp , changing exhausts , decat and hi flow filter did basically fack all as the Cam was the problem ... get the Cam fitted first.

[@ETSSNIPER]

Will it fit for T120 2021 Euro5 model?

[@georgemilburn6213]

yes

[@TotalAnomy]

I have a decated twin (1200HP engine) and I must say that if the newer bikes all come out with welded cats, that's just (one more) massive reason for me to not be interested in them.

[@georgemilburn6213]

it is not law yet, only some makers are doing it.

[@Wideangle11]

6 Hole Baffle is the best....
