Cecilt
Oct 16, 2015Explorer
Not sure if the MH exhaust is the same as the trucks but I have a 2009 V-10 and my performance had progressively gotten worse over the last 2 years. Lack of power, high RPM's to run grades that before I could drive without the high RPM's and lots of shifting. Turned out the catalytic converters were bad. Just got the truck back last week and it is like a brand new vehicle. Replaced under warranty as the Cats had an 11 year 120k mile warranty. Might want to check this.
