I’d recommend this over any exhaust on the market. Just because of living in California. More of an adult sound. Nothing to obnoxious. No drone what so ever!

The reviews don't do justice

This kit is amazing. Love the sound the flow is great. With big turbo its gonna be even better . Is silent and zero drone .

Really great exhaust, transformative!

Let me tell you i held out as long as possible because I didn’t want a drone prone exhaust. i’m currently running a big turbo and a 3” exhaust so my car had the potential to be very loud and with this system buts it’s not it’s very sporty sounding, but quiet in the cabin with almost no drone except for a hair on the highway going up large grades. i have my rear seats removed so noises from the back are louder anyways. There are no vibrations whatsoever and fitment as well as build quality are second to none. i tried an adjustable resonator 3” exhaust (cpe) and it was terrible like undriveable terrible and the fitment was poor because the exhaust had too many sections to properly align(4 vs 3 with fswerks). Also what FSWERKS doesn’t humbly mention is this exhaust features a MAGNAFLOW muffler and MAGNAFLOW resonator which is just icing on the cake as these are top of the line products. I payed full price and would pay more for the fit, performance and build quality supplied with this PREMIUM EXHAUST. it has an adult tone that can be enjoyed by any age. Buy this if you are even slightly considering any exhaust as it’ll perform in my opinion better than any other. Thanks FSWERKS, my wife will ride in my car again. ;).


Thanks very much for your feedback Seth :-)

St Stealth Exhaust

Very pleased. The exhaust was the hardest choice of any mod for me. Went with Stealth because I did not want to add 10lbs with the Miltek. Mountune sounded too stock and was 2.5" piping.On scale of 10 being loudest I give the exterior noise a 3 out of 10 and interior noise a 5 out of 10. Freeway 2 out of 10. It seemed too loud in the interior at first but I had my wife drive the car hard as I followed and it is nowhere near as loud on the exterior. This is most likely because I have removed the spair, foam and most stuff out of the trunk and it is a hatch. Very low deep tone. Perfect for those wanting a mature sound.

Love the fit and finish of this system and the sound is pure sex. It's deep and powerful without any drone or rasp which I was worried about. Makes the 4cyl sound like a bigger engine.
