I did post a picture in another thread; but I recently installed the Zard exhaust. I like the looks and the sound. It comes with a DB killer, which keeps the sound reasonable. It is also Euro 5 compliant and I did not have to fiddle with any mapping or get any sort of download.

Hi everyone. I have a 2023 Striple (carbon black to avoid confusion with newest models). I managed to scuff up the carbon fiber silencer so am taking it off to get it repaired. Meanwhile I bought an SC1-R (for 2017-2019) models but understand it’s compatible with the Euro 5 2023 model. Problem is that the link pipe in the photo wasn’t sent to me. The seller is looking for it and, if he can’t find it, will just do a return. But I’m wondering if any of you know if the link pipe will be an issue or if it’s something that I can have fabricated cheaply or use another 51mm mid pipe. Manufacturer’s photos, my bike, part missing in diagram and as it came. Green is the part that was included in the photo in the ad. Thanks everyone!

Hi guys. I bought the Spark exhaust, homologated with euro5 for my Street triple R 2020. Here are some videos with sound.
No remap, no other changes. Just plug & play. Feeling just in my opinion - with db killer - better throttle reaction, slightly more power on top and mid rpm, nice sound (not trying to destroy your ears). without killer - worse low rpm, worse throttle reaction, maybe little bit better top rpm (in this case, remap is necessary imho), very very loud (30min ride and my ears were bleding🙉).

Has anyone determined if an exhaust loop has any effect of performance? I would think that a loop would increase back pressure and torque. I'm between Spark and Scorpion for that reason.

From what I’ve seen on Dyno runs on YouTube those 2 systems without the DB killer have small gains only in the very top end and are somewhat worse across the low and mid range. With the DB killer they are a little better and certainly easier to live with from a sound perspective. But, as with most all of the slip ons they produce little or no gains versus the stock exhausts. So I guess it’s a personal choice for aesthetics and sounds you like, in addition to weight loss over the stock exhaust, will drive your choices. I have a Leo Vince with the DB killer and love the sound, deeper and still not too loud.

I think the SC Project is a full system, which means it replaces the headers too. The stock headers have crossover tubes and baffling (I think) which add backpressure that helps low-end torque. If you replace the headers, you'll get more peak HP at the top of the rev range, at the cost of low-end torque. The Zard is just a slip-on so it leaves the headers intact and therefore doesn't get as much of a peak HP gain but also doesn't sacrifice low-end torque. The only reasons why you'd want a full system are racing (where you're high in the rev range anyway) or volume (replacing the stock headers with what are effectively straight pipes will be loud). The Zard does come with a curved midpipe.

In reality, no one can actually feel a 2HP gain, so slip-ons are really for aesthetics (visual and acoustic).

Full disclosure... I am not an engineer

And yet, Im still going back & forth on whether to get a full system or slip-on.

Iv bought a 24 Street Triple and wen't with a oem header from the 20-22 Street triple and a Leiker exhaust.

Was unhappy with the performance, lack of power and the bike felt sluggis in the higher rpm range. Iv bought a rapidbike race module but i was unhappy with the riding experience in lower rpm range, trottle felt very sensitive and was on or off. I struggel to explane the experience.

I wonder if anybode els with the new street triple have had a simular experience after replacing exhaust?
Or what exhaust system have you guys used for the new street triple?
