MPI Exhaust Technologies

After doing my research and going through a lot of YouTube videos to hear the different manufacturers exhaust system sounds i found MPI exhaust so I took a chance Columbus did! And purchased the exhaust system. I had it installed at a muffler shop .Great price and great sound it doesn’t get annoying and the throttle respond improved also you don’t buy a tundra for the fuel mileage but am very impressed and the exhaust tips look good

Bought this MPI kit for my 2016 6.2L work truck Order Number #3274MPI. Total cost was $995 because I went with the full stainless. I really like the kit. Nice and mellow since I got the turbo's like they suggested. Had a couple questions and Kinzer walked me through then. 8/10 For easy of install on my garage floor. Bob was fairly quick for email response. Their is no drone as advertised which was why I bought this kit. My only complaint is they don't make more kits or all myvehicles would have a MPI Kit.

I put there system on my 2012 GMC, the best sound and performance I would have to say !! Plus awesome people to deal with !! The exhaust system is USA made and fits the truck the way it should with no mods to the underside!! I wouldn't hesitate to order another system from them ! Kinzer n Mike thanks for everything 🤙🕶

Only negative - the two bolts they sent to mount the collector were too short. So I used the original factory bolts. Problem solved. Everything else fit perfect. The install was "easy" for a senior citizen with multiple injuries working alone in his garage. This system sounds fantastic. Just a low throaty rumble from idle to about 30 mph and then it is just quiet. 10/10 would buy again.

I researched a lot for this exhaust purchase. I was impressed with the attention to drone reduction and how the system still retained a great sound. I furthered my research with reading all the materials I could before the purchase and even asking questions on the MPI FB comments and commenting on YT videos posted. All my answers pointed to no drone with this exhaust system. After getting this installed on my truck there is a unmistakable drone between 1500-2100 RPM. It raised the in-cab decibel reading over 10db in some places throughout that RPM range. For a system that is supposed to be "no drone guaranteed" this was certainly disappointing. To make matters worse, their customer service is next to non-existent. When I did actually speak to someone and explained my situation, they told
