FAQ
Will this fit my Dodge/Ram 2500/3500 with a 4" exhaust?
It’s a universal 4" bypass designed to replace a 36" muffler. If your system uses 4" tubing and a 36" muffler body, it’s typically compatible. Always measure your existing muffler and check connection style.
Is any welding required, or can I clamp it in?
Most installs are clamp-in if your system uses band clamps. Some setups may require light trimming or welding for best alignment and leak-free joints.
How loud is a muffler bypass compared to stock?
Noticeably louder with a deeper, more aggressive tone under throttle. Cruise drone varies by system and cab configuration.
What’s the difference between ARMOR LITE, ARMOR PLUS, and ARMOR PRO?
ARMOR LITE is aluminized steel (strong value). ARMOR PLUS is T409 stainless (higher corrosion resistance). ARMOR PRO is premium T304 stainless (maximum corrosion resistance and appearance).
Is this emissions legal?
Replacing a muffler typically does not affect emissions equipment, but sound and local regulations vary. Check your local/state laws before modifying exhaust sound.
