🛠️ Protect Your PowerStroke Before Disaster Strikes!

At Mulitia Muffler, we install S&S Diesel Motorsport Disaster Prevention Kits for Ford F-350 6.7L Power Stroke trucks! And we have lots in stock!

The factory CP4 fuel pump can fail, sending metal debris throughout your fuel system and potentially causing thousands of dollars in repairs.

💥 Why install a Disaster Prevention Kit?
✅ Helps prevent metal debris from reaching your injectors and fuel rails if the CP4 fails.
✅ Reduces the risk of extensive fuel system damage.
⚠️ Don’t wait for a fuel system failure!

Plastic out. Pusher Bronze in 🔥

We just swapped the factory charge pipes on this Powerstroke for a full set of Pusher hot and cold side charge pipes, and this engine bay looks unreal now 👀

Why it’s worth it 👇

💥 The factory plastic charge pipe is known to crack and leak boost
🔩 These are 3” mandrel-bent steel, fully TIG welded
💪 Built to hold way more boost than stock
⚡ Sharper throttle response once it’s all sealed up

All finished in that Pusher Bronze powder coat from Pusher Intakes 🤌

This is the diesel performance side of Mulitia Muffler. Charge pipes, intakes, tuning, exhaust, wheels, lifts, the whole build 🛠️

Your diesel can keep running even with the key OFF. 😳

That’s a diesel runaway, and it’s exactly why so many oil and gas workers run an EPASS on their truck 👇

🛑 EPASS = Emergency Positive Air Shutdown
⛽ Out on site, gas vapour from a leak can get sucked into your intake
🔑 Your diesel burns it as fuel, so turning the key does nothing
🔥 The engine keeps revving itself until something gives
✅ An EPASS snaps the air intake shut and chokes it out in seconds

A lot of our customers working the patch around Fort St. John won’t drive without one. Your truck’s too important to leave it up to luck. 🚧

We install them right here at Mulitia Muffler, along with everything else your diesel needs. Performance upgrades, tuning, lift kits, wheels and tires. More than just a muffler shop. 🔧
