Help Guide: Triumph Street Scrambler 900 & Hitchcox Motorcycles Shotgun Slip-Ons
How to choose the right aftermarket exhaust set up for your Triumph Street Scrambler 900
So you've picked up a Triumph Street Scrambler 900 (2017 to present). It's a gorgeous Triumph motorbike with that iconic high-mount exhaust. Now you want to upgrade even more…
Upgrading to Hitchcox Motorcycles slip-ons is one of the most popular first mods for new riders. It's an easy bolt-on project that transforms the bike's character without requiring a mechanical degree. Here is everything you need to know before hitting "buy" on your Triumph aftermarket exhaust upgrade.
1. Understanding Emissions: Euro 4, 5, and 5+
The most important step when choosing a Triumph exhaust upgrade is identifying which Euro standard your bike meets. This determines the fitment of the slip-ons.
Euro 4 (2017–2020): These models have a slightly different internal fuelling map and physical mounting points.
Euro 5 (2021–2024): Triumph updated the engine and exhaust to meet stricter emissions standards.
Euro 5+ (2025–Present): The latest standard. While the engine remains similar, the sensors and exhaust housing have slight variations.
Why it matters: Hitchcox Motorcycles designs specific kits for each of these brackets. Check your V5 document or the manufacturing plate on the frame to make sure you select the correct Triumph exhaust version for your year.
2. The Catalytic Converter and Your Triumph Aftermarket Exhaust
A slip-on exhaust replaces only the mufflers, the end cans. These Hitchcox Motorcycles units are designed to retain the factory catalytic converter (the "cat").
The Benefit: Since the cat stays on the bike, you don't need to remap your ECU (the bike's computer). The bike will still run smoothly straight away, making this the simplest Triumph aftermarket exhaust upgrade available.
The Sound: Even with the cat installed, these Triumph exhaust slip-ons deliver a much deeper, throatier thump than the restricted stock silencers.
3. Choosing Your Finish
Hitchcox Motorcycles offers two primary finishes to match your Scrambler's vibe:
|
Finish |
Aesthetic |
Maintenance |
|
Brushed Stainless |
Classic, raw metal look. Matches the silver accents on the engine. |
Very durable. Minor scratches can be buffed out with a Scotch-Brite pad. |
|
Ceramic Black |
Stealthy, modern, and aggressive. Great for blacked-out builds. |
High-temp coating. Extremely heat resistant, but requires careful cleaning to avoid chips. |
4. To dB Killer or Not?
The dB Killer is a removable metal baffle that sits inside the end of the Triumph exhaust to dampen the volume.
With dB Killer (Street Friendly): Provides a refined, bassy tone. It's louder than stock but won't annoy your neighbours at 6am. Perfect for long touring where “drone” might get tiring.
No dB Killer (The Growl): Removing the baffle opens the airflow, resulting in a much louder, more aggressive bark and some satisfying pops on deceleration.
New Rider Tip: We recommend starting with the dB killers installed. If you find it too quiet, they are easily removed with a single bolt. It's much easier to make a quiet pipe louder than the other way around!
