So I installed FSWERK's Stealth Exhaust on my 2014 Sedan, but I don't have a tune. I was wondering how much power gains should I expect if I get a proper tune? Thanks

You probably won't see much gain since 1) you still have the stock exhaust manifold so it still bottlenecks at the smallest point and 2)without a tune, your engine will ignore it's extra potential and continue to try to drive as if it was stock

Maybe 1-2hp and noise. Header is restrictive.

Meaning the exhaust manifold....Add a tune & you'll find the engine more linear, smoother, responsive....

Best power gain you can get with that combination.

ASSUME you already did a replacement air filter and snorkel delete?

Yeah I've deleted my snorkel and got a K&NFilter (openBox) plus the MST intake hose.

Also, s the open box mod bad?

Yes, IMHO, since at low speeds you'd get warmer engine compartment air ingested.

ONLY useful for added noise - reduction for power.

okay thanks, I've been planning on doing something about that like getting the AIRAID or the ROUSH or the RS cover but I can't find anyone who sells it with out the filter.

highly recommend the airaid intake paired with a ford racing snorkel or velossatech snorkel. been running one on my car for 3 years now and intake temps are normally about 5 degrees above ambient temp. that box extension shield that the airaid comes with does a great job keeping the engine bay heat out.

if you go with airaid only suggestion is to swap out the gasket seal they have at the top of the extension. the one it comes with is like a blade style gasket and will cut into the fire blanket on the hood. i swapped mine out for a bulb style one and it works better. looks like this.

Is there anywhere I can get it without the filter?


Nah it comes together as a kit. But it’s never a bad idea to have a backup air filter.
