    Sounds awesome on my 500hp Cammed fbo LS silverado! Like the straight through design so there is minimal to no power loss compare to chambered mufflers that choke your engine... hasn't blown the packing out as the cheap one do and sounds better overtime. They can be a bit quiet for the first 500 miles or so but wakes up after seasoning. It welded in good and is mellow while cruising and growls when you're in it. The quality was spot on as I've been running these for years and had about 8 so far. Can't go wrong with magnaflow! Get one, you won't regret it and the price is great!

    It's a genuine magnaflow. Originally bought with the intent of swapping with factory muffler using factory exhaust piping. Ended up exchanging with a 3inch in/out and doing all new piping. This is a 2.5 in/out in case you aren't aware. 14inch body mufflers are fairly loud, but have a good sound. Straight through design, so no performance loss. Glass pack muffler essentially. Google it if you aren't sure what they look like inside. Has a slight break in period that will vary depending on your driving. Mine take a while since I don't drive much daily. Had magnaflows on previous vehicles and continue to use them. My only gripe was this came in the original box like you'd find on a shelf at your muffler store. Didn't have any packing material around it to keep from getting damaged. In fact the box flap wasn't even taped shut. Got lucky in my case that it was closed and all the paperwork was still there. No dents or dings. Scratches weren't a concern since this is a muffler after all. If it was the polished model for a show car I would be a little more concerned.

    Used this product before.
    Easy installation.
    It's just a muffler. Not going to gain any horsepower, but your engine will have no back pressure. Maybe a couple of miles per tank full better fuel economy. Nice DEEP rumble. Not super loud on cold start. Actually this is a decent muffler if you are going for sound

    5.0 out of 5 stars with a nice single oval-ish tip
    Reviewed in the United States on February 18, 2015
    Ordered this for my 2014 Fiesta ST, had the shop mount it in the stock location, turned 45 degres, with a nice single oval-ish tip. It was O.K. but barely louder than the stock muffler. I went back and had them cut off the triangular resonator just after the downpipe. This really made the difference. It is a nice tone, nothing too raspy, and there is no drone whatsoever. If I behave it is just barely there, if I nail it, the sound is moderate and pleasant. Hope to get a GoPro soon for a demo video. If you are doing this to your Fiesta ST, I would recommend taking off the resonator at the same time to save labor charges. Don't expect 20 horsepower, you won't get that from a full 3" exhaust at 3x the price of this combo.
