FSWERKS St. Stl Stealth Exhaust System - 2018 FoST

FSWERKS were uber-professional and steered me away from the Race exhaust to the Stealth version of the same 'cos the CA rules on exhaust-loudness changed days (i.e. 01/01/2019) before my purchase.. and what a hoot it (still) is! Soundtrack-fun to & from the office every day (running a Stratified Stage 1 with Rice Crispy's Snap! Crackle! & Pop! LEN add-on) Also, I'd requested the return of my OEM system (destined for storage). Instead of simply throwing it in the trunk and dinging everything in-sight, the FSWERKS crew wrapped everything (and armored the sharp-tube ends) before carefully(!) placing it on butcher's-paper delicatey on the

A 3” exhaust is pretty much a 3” exhaust, they all sound basically the same depending on how much or little car/resonator/muffler there is. On my ST I have a catless dp running into this catback and the sound is about what I expected, it gets droney a bit under load around 3k, everything does, but otherwise it’s tolerable as a DD. If you drive easy it’s not loud inside the car. Might annoy light sleeping neighbors but otherwise it’s fine. Get on it and everyone knows what you’re doing though. The reason I’m leafing the comment is the fit and finish, which was perfect. I’ve never bought an expensive pre formed stainless exhaust before that went on out of the box without any massaging, but this one did. Whatever they are using to mock these up is perfect because the thing went onto the car with the hangars and bends all perfectly aligned. A+, as good as it gets.



I was a bit worried the exhaust was going to be too loud especially with "race" in the name. It's the perfect level for me even with a catless downpipe and a gtx2971r. Everything fit great and sounds perfect no rasp which I was afraid of being catless.

love this exhaust

Can't beat price even before I added my downpipe this exhaust sounds amazing. If you aren't looking to go straight pipe add a downpipe or just not have drone this exhaust is perfect. Vic hooks it up
