Excellent quality product, easy to install and lifetime warranty. The lowest price you will find anywhere for this system on the internet. Have already noticed improved mileage and performance!

I installed my mbrp exhaust system on my 2007 Dodge Cummins 6.7 liter. Direct bolt on behind particulate filter .I noticed immediately a better turbo spool up and better throttle responce at highway speeds. Not sure of fuel economy yet. With no factory muffler I was concerned that it would be to loud, noticed very little difference in loudness.

The directions were clear and the installation was easy. It took only about 30 minutes with hand tools. I don't know that there will be much actual performance/mileage improvement as the factory exhaust is already 4" and the muffler is straight through design. Only real differences are mandrel bends, the elimination of the factory muffler, and the polished tip.
