Good but not great
I went the cheap and easy route and all got was hard and cheap and weak. Overall the sound is beautiful but rather toned down for what I was expecting. Maybe with time it will gain some but that is hard to tell. The install was ridiculous. The kit I received was nowhere near long enough. Fitting was basically a custom job on my part. The good news is that they look like classic flowmasters. Appearance was for sure not lacking. Next time I'll explore other options.
Ordered from Autoanything.com....awesome. Timely shipping. Tried to install, passenger side ok....drivers side improperly welded too wide to fit between block and frame. Tried to RMA/Exchange....polite people at MagnaFlow who talk nice but don't do their job. Based on my experience, don't buy MagnaFlow if warranty and customer service are important. A week and a half and no RMA#. If you have a warranty issue don't look for fast resolution (if any), beware of buying MagnaFlow online.
Not a TRUE Cat Back
This system is NOT a true cat back. I have a 2013 f250, with the 6.2 gas motor. What they say it is, and what it really is......different. You leave the front muffler on, on this system......not a TRUE cat back. How they tell you on the instructions to install the system.....not going to happen. Spend the extra money and get a good system. I would NOT recommend MBRP
