Uniquely engineered for the S550 Mustang GT, our range includes a Header & Cat Kit as well as a Cat-Back System which can be combined to achieve the ultimate in performance and sound.
Featuring a tuned length design and 100-cell high-flow metallic cats, our headers increase power throughout the rev range whilst also assisting the 5.0 V8 to produce a spine-tingling note.
The Cat-Back system is a direct replacement bolt-on upgrade which features 3-inch pipework, 304-grade Stainless Steel construction and an X-pipe to help produce a high-pitched exotic tone.
Combining precision fitment with style and most importantly, practicality; thanks to our very own VAREX Valve Technology.
VAREX puts you in full control, allowing you to adjust the exhaust output from a classic mellow street friendly sound to a race car growl at the push of a button,or opt for the optional SmartBox to have complete control from your phone via the XForce app.
Precise manual adjustment, at the touch of a button. VAREX SmartBox is an optional control device with patent-pending technology that lets you manually or automatically adjust the exhaust sound level of your VAREX exhaust via your smartphone.
