Frequently Asked Questions

What is the difference between a cat-back and turbo-back exhaust system?

A cat-back exhaust replaces the piping from the catalytic converter to the tailpipe, including the muffler and exhaust tip. A turbo-back exhaust replaces everything from the turbocharger downpipe to the tailpipe, including the catalytic converter or DPF on diesel trucks. Cat-back systems are the most common upgrade for gas trucks like the F-150 5.0 and Ram 1500 HEMI, while turbo-back systems are typically used on diesel trucks like the Cummins 6.7 and Power Stroke 6.7 for maximum exhaust flow and performance gains.

Does an aftermarket exhaust system increase horsepower on trucks?

A cat-back exhaust system on a gas truck typically adds 5 to 15 horsepower by reducing backpressure and improving exhaust flow. On diesel trucks, a turbo-back or DPF-back system paired with a cold air intake and tuner can unlock significantly larger gains — sometimes 50 horsepower or more depending on the platform. The biggest gains come from combining an exhaust system with an intake from Air Intake Systems and a tuner from Programmers.

What is the best performance exhaust for a diesel truck?

MBRP and Flo-Pro are the top-selling diesel exhaust brands in Canada, offering 4-inch and 5-inch systems in aluminized and stainless steel for Cummins, Duramax, and Power Stroke trucks. For aggressive sound and maximum flow, a 5-inch stainless system with a straight-through muffler or muffler delete is the go-to choice. For a quieter diesel exhaust with strong performance, a 4-inch system with a performance muffler delivers the right balance of flow and cabin comfort.

Is a DPF delete legal for trucks in Canada?

DPF delete legality varies by province and use case. In most provinces, removing the diesel particulate filter is not legal for vehicles driven on public roads and may result in failed emissions inspections. DPF delete kits are typically sold for off-road, competition, or agricultural use only. Check your provincial regulations before purchasing, and consult with your local inspection authority for specific requirements in your area.

Is MBRP or Borla a better exhaust brand for trucks?

MBRP specializes in truck and diesel exhaust systems with a focus on durability, flow, and value — offering both aluminized and stainless steel construction. Borla focuses on premium stainless steel exhaust with tuned sound profiles like the ATAK (aggressive) and S-Type (refined). For diesel trucks, MBRP is the dominant choice in Canada. For gas trucks like the Ram 1500 5.7 HEMI or F-150 5.0 where exhaust sound character matters, Borla ATAK and S-Type systems are a top-tier option.

Do exhaust tips change the sound or do you need a full exhaust system?

Exhaust tips alone change the visual appearance of your tailpipe but have minimal effect on exhaust sound or performance. A larger tip may slightly deepen the tone at idle, but it will not produce the sound or performance gains of a full cat-back or turbo-back exhaust system. For a noticeable change in sound and power, a full exhaust system with a performance muffler or muffler delete is required.
