MPI EXHAUST TECHNOLOGIES
FAQ
Improve your truck's performance and gas mileage with one of our patent-pending exhaust kits.
Turbo Series mufflers or Performance Series?
- Both our MPI Turbo Series mufflers and MPI Performance Series mufflers are very high-quality products well suited to your exhaust needs. However, the two have some key differences that may affect your preference. Turbo Series mufflers are more mellow with less rumble, a tad more reserved than Performance Series. Performance Series on the other hand have a bit more growl to them indicating their increased performance with a more aggressive tone heard at the tailgate and a bit in the cab. When used with our Pulse Chamber system, neither of these mufflers creates an in-cab drone and will make your truck sound the way it should!
Do we use Stainless or Aluminized pipe for our systems?
- We use Aluminized pipe for our systems. An aluminized pipe will last 10+ years easily if you wash your truck's underside every so often, and it performs very well compared to stainless steel but at a lower cost to you.
Our Aluminized Steel pipe's raw material undergoes a continuous hot-dip process, building a coating across every millimeter of the surface.
Hot-dipping results in a tight metallurgical bond between layers of an aluminum-silicon alloy and the pipe’s steel core.
- The final aluminized pipe possesses a combination of enhanced properties: the strength of steel sheathed in the corrosion resistance of aluminum and the heat protection of aluminum-silicon alloy. It also performs quite nicely against exposure to salts.
Installation
- Installation is quite easy. We do recommend someone with welding experience take on the welding. Your local muffler or exhaust shop will be willing to help as well. Installation is very straightforward. We recommend any person seeking additional information on installation go visit our YouTube page to watch some of the installs. We have had customers use exhaust clamps for the installation. We recommend welding but you can make the final decision.
Increased Fuel Economy
- Our exhaust kits provide increased fuel economy through the elimination of back pressure in your exhaust system. This is done through a less restrictive exhaust system with improved flow, yielding more power. More power means less throttle usage and an increase in fuel economy. However, with the way your truck will be sounding, it will be hard to stay off of that throttle!
*The only times we don't see fuel efficiency increases are when there are substantial mechanical issues with motors.*
Will the kit fit my truck?
- Our exhaust kits are designed to fit the maximum wheelbase of each truck model/year, and can easily be trimmed to fit shorter styles of trucks by following the measurements provided with each kit.
Will this void the factory warranty?
- This is an often asked question. No, it is illegal for a dealer to deny you the warranty because you have changed any exhaust from the catalytic converters back. MPI does several trucks per year for the local GM and Dodge dealerships before the trucks are sold to customers.
Is there a warranty on the mufflers in your kits?
- Great question. Both our Turbo Series mufflers and the Performance Series mufflers have a 3-year limited warranty.
