was wondering if anyone else had a flowmaster or any type of exhaust on a ecoboost and how does it sound?

 

Search You Tube for "f150 ecoboost exhaust clips". There are TONS of them.

 

I recently just purchased a 4in Heartthrob Exhaust I am currently awaiting its arrival. Supposedly adds a bunch of horsepower. And it sounds cool as hell! You tube 4in heartthrob ecoboost.

 

Yes, but at the end of the day, it still sounds like a ticked off Bumble Bee.

I have owned V-6 and I-6 trucks, and the best sounding muffler I found for either, is a Dynomax Super Turbo muffler. And, Dynomax has a lifetime warranty.
