Amazing Exhaust!

Been running with the exhaust for a few months and I love it! Makes the car sound a bit meaner and louder! Get some pops when shifting or downshifting if done just right! No drone! Drove for two hours to Santa Barbara and the whole drive was comfortable with no drone. It sounds amazing in the mornings on a cold start. Not to loud unless you want it to be, then floor it! Great exhaust!

Great System ... No Disappointments

Product delivered exactly as in photos. Took me 2hrs to install since I had to use a hacksaw to cut the OEM tailpipe. Installation was a breeze with the pipes sliding together without any issues and the heavy duty clamps. I ordered a aftermarket exhaust gasket and the COBB hangers, but since this system is lighter than the OEM system, the OEM hangers probably would have been fine. I extensively researched the systems on the market before deciding on FSWERKS. I was looking for verified torque/HP benefits with a mild increased sound. It's exactly what I wanted. Thank you FSWORKS.

Great system and works with trailerhitch

Called 1st to ask questions. I have the trailer hitch installed. The guy I spoke to upfront honest said he didnt know how the system would work with the hitch. He gave me measurements, checked and took a chance. No worries it goes together better than with stock exhaust. I had knocks on rough bumps with stock. None with fswerkz system. Again sound great worth every penny. Super easy to install. Instructions dead on.

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!
