This exhaust is exactly how it's described. It fits as it should everything went in to place very nicely and installed in about 1.5 hrs with no help from anyone. It has a nice tone to it but it's loud as it states it is. I think it's almost too loud for a daily driver but man does it sound mean. Order arrived on time took about 3 days to get after the order was placed. Good product and fast shipping

If you want loud this is the way to go. Put on a 2019 F-150 V8. Instalation was fairly easy. Quicker with 2 people. Only trouble was the exhaust tips are too tight of fit. Had to hit with a rubber mallet and still not perfect. Quiet going down hill or while causing but will hear you in the next county when you step on it.

This kit is SICK!!! Just finished installing on my 2017 f150 and OMG am I impressed. Install was straight forward and fit perfectly. Decided to go with the straight out the back and all the necessary pipe and fittings work perfectly. Talk about sound!!! this kit will make everyone notice you and the Mustang next to you will be envious. The power and throttle response is impressive. I can't say enough about this kit. If you like loud, throaty, and aggressive this is the kit for you. Honest install time with no rack and basic tools is 2 hours.

The exhaust is well built. On pipe was bent in shipping. Little pain install. But not system falt. The sound on the eco v6. Sound level is fine. But sounds like a rice burner. Not in love with. But it's not a v8. Thinking changing muffle .to get a deeper sound. If possible. Over all a great system .tips are awesome.

Installed on my 2016 F-150 Lariat 502a. They are louder than I thought but wow do they sound good. A little worried when someone is standing to close to the truck when I start it. It makes people jump a little bit. If you are at all worried about them being too loud than they probably are not for you. I love the sound though it sounds amazing, just not for someone that wants a nice rumble. If you want to turn heads going down the road there is not better exhaust IMO than the outlaw.

It sounds great on my 5.0L, and I like the look...however, I spent far longer than I should have trying to install this. Everything slid together nicely, but I question the QA/QC of these parts since the clamps either weren't compressing the pipe enough to secure it, or the pipes were not the right size for the clamps. I don't suggest anyone get this unless they can easily pop a tack weld themselves

STUPUD LOUD! The reviews dont lie. Looks great. Sound is great. Rich, deep growl. But maybe too loud. Any video you watch will not do justice on how loud it is. If you're concerned pissing off neighbors or disturbing anyone. This is NOT the exhaust for you. If you want a true head Turner. This exhaust is your answer. Installed on 2016 F150 5.0L resonator delete

Sounds awesome and definitely will piss off the neighbors. Does have a drone in the cab but it’s not bad on the highway

It was easy to install once you have all the hardware I hope it was just me that was missing hardware and hangers
