If you're in the loop, you know the B9 Audi S5 is the next-gen upgrade from the OG B8 S5. Rolled out in 2017 and is still killing it in the market. Built on Volkswagen Group's MLG platform, it's rocking a 3.0 single turbo TFSI engine which makes decent horsepower, but we're here for more.
Fresh out the gate, this beastly 3.0 TFSI with its twin-scroll turbocharger is pushing a solid 349 hp and 369 lb-ft. And yes, it's both lighter and packs more punch than the supercharged 3.0 V6 from the B8 S5 days.

Can Auto Performance was born out of a passion and a problem. Two buddies, both mad about their B8 S5s, were constantly let down by test pipes that would crack, sound off, or rust out. Frustrated but fueled, they decided to change the game. That's how CAP stepped up, crafting the world's premier test pipes and putting Canadian Auto Performance on the map.
At our core, we've always been Audi addicts with a soft spot for top-notch mods. We just needed a space dedicated to German car tweaks, so we made one. Today, if you're talking Audi mods, we're the go-to authority. No question about it.

Downpipe is what sits between your turbo and the entire exhaust system. The factory standard? It comes with a restricting catalytic converter. While it's great for keeping emissions in check, it's not the best mate for optimal engine performance.

Now, if you're thinking a downpipe alone is going to skyrocket your car's power, hold that thought. On its own, the gains might be modest. But bring in a tune and some quality bolt-on mods, and you're looking at a potential power boost of 40hp+.

The catless vs. high-flow catted downpipe debate is all over the internet. Here's the bottom line: if you're in a strict-emissions state, play it safe with the high-flow. If not, the catless is your ticket to minimizing back pressure.

We’ve done a ton of research and design to ensure your car gets the maximum airflow and performance boost. Our B9 S5 downpipe is tried and tested. Don’t take our word for it, the whole internet is buzzing about our downpipes and test pipes being the best!

Jumping into the deep end of aftermarket debates, let's chat about cold air intakes. Look, we're all for mods – the more the merrier. But let's be real, the price tag can sometimes be a hard pill to swallow. That's where we come in.
Our B9 S5 cold air intake system isn't just about aesthetics or performance – it's about delivering both without burning a hole in your pocket. Tailored for the Audi B9 S5, this beast not only amplifies that addictive turbo spool soundtrack as you cycle through gears but also ensures a fresher, cooler air supply, making your ride look and feel more or less like an RS5.
But wait, there's more. The magic of a cold air intake is truly unlocked when you pair it with a turbo intake pipe that's all about flow, topped off with a Stage 1 ECU remap. Combine these, and you're not just driving a car, you're commanding a powerhouse straight out of the box.

When contemplating an ECU tune, it's worth noting that there are numerous at-home options available online.

When it comes to the pursuit of real power in your vehicle, one mod that often flies under the radar is the aftermarket intercooler. Now, let's get one thing straight. Never expect a B9 S5 Intercooler to be the power booster on its own. It's not the typical performance mod; it's more about enhancing reliability and efficiency. Read more on the benefits of upgrading your intercooler for Audi.
What sets an aftermarket intercooler apart is its size, with options like Canadian Auto Performance B9 S5 intercooler boasting a whopping 134% increase in surface area compared to the factory version.
Well, more power in your engine means more heat production, and that's where things can get tricky. Heat soak, the Achilles heel of power gains, starts creeping in when you push your engine harder. If you're genuinely committed to unlocking more power and ensuring your engine's longevity, investing in an aftermarket intercooler is a must.
To wrap it all up, we also recommend our RS5 Bumper & Honeycomb Grill, a mod that instantly transforms your car's appearance, giving it the sleek look of the RS5. It's often the first choice for many enthusiasts and stands out as one of the finest exterior upgrades you can make to any S5.
