Couple things about this kit.

1. The turbo and BPV noise is slightly more noticeable.

2. Cut your factory exhaust just before the portion that goes over the rear end to simplify the install.

3. ZERO drone at cruising speed 45mph and 70mph.

4. Factory piping measured 2 1/4 inches. This cat back measured 2 3/8 inches.

Exhaust audio is always hard to capture but I tried my best with a GoPro.

Sounds good. Very little popping with you blip the throttle. The Focus ST is a nice car.

Nice, hope this car starts pulling in the young import kids, crowd.

I can imagine that it is really appealing to the import crowd, but that isn't why I bought mine!

Was there any gain in power? Sounds decent, how does it sound in person?

Doubtful. The factory piping is 2 1/4 inches and the Magnaflow measured at 2 3/8 inches. I mainly did it for a little more sound on the DD.

Thanks. I think it makes a great daily driver. I wish I could have the interior of this car in my Z:D

not a fan of any aftermarket exhaust for the ST so far...

And thats coming from someone who will own one in a few weeks!

I'll be leaving my exhaust stock on my ST...bought it for a fun quiet DD, lol don't need another noisy ride.
