Flowmaster 817752 Outlaw Axle Back for 07-18 Jeep Wrangler JK

Horrible sound. LOUD. Made my Wrangler sound like a tuner Honda. Every hill was torture, as it would drone the interior out. Getting on it sounds like there is no muffler at all. This product sucks. I had it on for a week, then ordered the Magnaflow. The top of the Flowmaster already had a huge section of paint gone and was starting to rust. Horrible product.

Superrrr. Like the sound. The Jeep has a little more horsepower too. Great.

First the good part: The sound is awesome! Yes it's loud but that's what Flowmaster is famous for so if you buy a Flowmaster, you obviously want it loud! You won't be disappointed! I was happy that there weren't any chips in the ceramic coating!

Now the frustrating part: You may or may not know that Holly Performance acquired Flowmaster in February 2019 and they still seem to be sorting things out a little bit..They did change the way the exhaust tips attach to a clamp instead of the set screw method people were complaining about in past reviews but, the nuts and bolts they supply for the clamp don't match. The nut is one size too big so when you start hitting the resistance of the clamp tightening, the nut starts slipping threads. It's just a quick run to the hardware store but it's just frustrating that simple mistakes like that are made in what is expected to be a quality part. And speaking of simple mistakes, another complaint I saw in earlier reviews was concern that the left hanger would slip out of the bushing since it didn't have the retaining knob like the factory hangers have. So their method of addressing that concern was to include a "push-on hanger keeper" to keep the hanger from slipping out of the bushing. It's actually one of those friction washers and it would be a simple, workable solution...if they included the right size. The hanger keeper they included was way too big and didn't grip on the hanger at all. Sure, I'll pick one up at the hardware store while I'm there to get the right nuts for the exhaust tip bolts but, again, it's just frustrating that they can't get it right. So I deducted a star.

Over all, I'm very happy with the product. When they get the small issues corrected so the customer doesn't have the frustration of having to run to the hardware store, it will be a solid 5 star performance muffler!
