I like this exhaust

Easy to install. Sounds awesome! It's not too droney on the highway, but makes the car sound more aggravated than stock.

Fiesta St Exhaust

I'm a 74 year old rodder, now reduced to driving a tuner, hahaha....needed a little punch & exhaust note for my little ST, so went with a FSWERKS cat back system. Easy installation, quality system, not too loud, exactly what I was looking for. Would recommend it highly to anyone!

Sport exhaust system

10/10 fitment. The sound is low deep tone and has no drone at all which is good, but I do wish it was a bit louder on wide open throttle. Other than that, cannot complain at all. Fit on 2019 FiST

Awesome exhaust

All the awesome noise you want with zero drone. It gives a lot of burgles on deceleration and the cold start was more aggressive than I thought would be too. Changes all the noises in the best ways without the drone and I couldn't be happier. Cheaper than many other name brands out there which is a huge plus. Paired with a Whoosh catted downpipe
