If you want loud this is the exhaust u need.
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 ... show more

Not in love with sound on a v6. The sound level is fine .
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. ... show more

Very loud and aggressive beefy sound
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. ... show more

Loud is an understatement.
This exhaust is LOUD. It will 100% wake the neighbors. When they say “aggressive sound.. they aren’t joking. Install was pretty quick on my 2018 f150 xlt 5.0. First exhaust arrived damaged.. mike with revel immediately shipped out another exhaust and I had it in 3-4 days. Kept me in the loop every step of the way. Hands down some of the best customer service I’ve gotten in a while. If you’re wanting the loudest exhaust for your truck.. this is it. Side note.. when going from the stock single exhaust to this dual exhaust.. it will be louder for sure, but you will lose some power at lower rpms. Just food for thought. ... show more

Great look/sound, questionable part quality
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 ... show more

Unbelievably loud
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.
