STOP LEAVING POWER ON THE TABLE
Your Mustang, F-150, Bronco or Explorer ST left the factory with a lot of potential and a very conservative set of instructions. We specialize in the former and have zero interest in the latter.

The complete guide
Not Sure Where to Start?
The S650 Mustang GT is one of the most buildable platforms on the road right now. The Coyote 5.0 responds to almost everything you throw at it — and the aftermarket has had plenty of time to figure out exactly what works.
The problem isn't finding parts. It's knowing which ones to buy first, what to pair with what, and what order makes sense for your build and your budget. Do you go exhaust before headers? Tune before or after the intake? Is a supercharger realistic before you sort out the fuel system? These are real questions that don't have generic answers.
Our Mustang Mod Guide covers every major upgrade category: cold air intakes, performance exhaust, long-tube headers, superchargers, fuel systems, suspension, wheels, and styling. For each one, we break down what it actually does, what gains you can realistically expect on the S650 platform, and which products we recommend — and why.
Whether you're starting with your first bolt-on or already planning a 700whp build, this is the starting point. Read it once and you'll know exactly where your build is headed next.
Every Build Earns
Sign up and we’ll drop 250 points in your account before you buy a thing. After that, every dollar you spend earns points toward your next order — discounts, free shipping, or actual Lethal Performance gear.
The more you build, the more you earn. Lethal Rewards runs four tiers — Bronze, Silver, Gold, and Platinum — with earning multipliers that scale as you climb. Hit Platinum and you earn points at 2x and get free shipping automatically on every order.
The car’s never done. Neither is the earning.

Through Ford dealerships or an authorized Ford Performance distributor. Lethal Performance has been an authorized dealer since 2004. We stock Ford Performance parts for Mustang, F-150, and Bronco and ship nationwide.
Depends on the part. Ford Performance parts are engineered and validated for your exact platform, which matters for things like camshafts and crate engines. For bolt-ons like exhaust and intakes, aftermarket brands sometimes give you more per dollar. Call us and we'll tell you which is which for your build.
On a Coyote V8, a custom tune is the biggest first gain, then intake and exhaust, then forced induction if you want serious power.
Ford Performance is Ford's own performance parts division. Aftermarket means everyone else: Whipple, Kooks, BMR, Steeda. We carry both and we'll tell you honestly when the OEM part is the right call.
No. Mustang is where we started, but we carry deep collections for F-150, Super Duty, Bronco, Bronco Raptor, and Explorer ST (including Whipple kits for the trucks).
