With our stamped logo on the tip and our unmistakable styling, there's no question that you have the hottest performance exhaust on the road - MBRP.

Review: Loud, even for the 2.7L - Simple to put on, very happy with the quality, shipping was faster than expected even around the holidays. It is a little loud for what I was expecting, but the the exhaust still sounds awesome in my opinion for a turbo v6.
Review: Not a bad sound fo a 3.5 v6 - Overall I like the sound yes I know you won't get that true v8 sound with this system but it does have a nice tone with it. I went had it installed professionally I probably could've done it myself but didn't have the lift . And I don't trust jack stands not when you have to push and pry off the old exhaust.. but Overall I'm happy with the exhaust and I just order an 8in tip for it I like the 5in it came with it but... I miss my big tips that I had on my old truck.

### ⭐ Easy install bad sound
*by J***. on October 7, 2020*

The exhaust was Easy to install on 2017 f150 3.5. The sound was horrible! With the 10 speed the sound is all over the place. Hondas sounds better than my truck did which says alot. I had it on for less than 24 hours before I put stock exhaust back on.
