2021 3.5 ecoboost pro armor race series

Sounds great to me. Has a nice deep mellow exhaust tone throughout all ranges of rpm’s.Not to loud and doesn’t have that crackling or real raspy note at the end when heavy on the pedal. You will get some cab noise, it’s definitely not gonna be dead silence like it was before with stock. The cab noise isn’t bad at all, the loudest it’ll get inside is when I’m in the lower gear range and it’s hanging out on the higher end waiting to shift. Once up to a maintained speed it’s a very light mellow note.

Rawr bueno

Not too much sounds and not too little. Just the right amount of rawr. You may have to buy fully threaded flank bolts though because the ones it came with do not have threads long enough to tighten, atleast on my truck. Also you may have to cut piping depending on your year make model and bed length.
