Performance Headers That Wake Up Your FJ Cruiser Exhaust

The exhaust header is where performance gains start. Replacing your stock manifold with a performance header reduces backpressure and helps the 4.0L V6 breathe more freely, which translates to better throttle response and more power across the RPM range. 

We carry stainless steel and silver ceramic coated options from trusted names like JBA, giving you a choice between raw durability and superior heat management for trail and street use.

Cat Back FJ Cruiser Exhaust Options for Sound and Flow

A cat back FJ Cruiser exhaust system replaces everything from the catalytic converter outlet to the tip, giving you the biggest change in tone and flow without touching emissions equipment. Our cat back selection includes systems from Magnaflow and JBA, both known for a deep and aggressive exhaust note that suits the FJ Cruiser on and off the trail. Here is what sets these systems apart:

  • Magnaflow cat back systems use mandrel bent stainless steel tubing for maximum flow and a smooth, even tone across all engine speeds.
  • JBA cat back systems are precision engineered for the 2007 to 2012 FJ Cruiser 4.0L V6 and built to increase horsepower while delivering a more aggressive exhaust note.

Both options bolt on directly, making the install straightforward for anyone with basic mechanical experience.

Mufflers, Resonators, and Weldables for Custom FJ Cruiser Exhaust Builds

Not every builder wants a complete system - some just want a standalone muffler or other parts. Our Pro Flow muffler lineup comes in 2.25 inch and 2.5 inch inlet sizes in satin and polished stainless finishes, with standard and three chamber designs to dial in your preferred tone. 

Resonators smooth out the exhaust note for those who want performance sound without highway drone. Weldable components give fabricators the raw pieces needed to run custom routing on lifted or heavily modified rigs.

Gaskets, Hardware, and Odds and Ends That Complete Your FJ Cruiser Exhaust System

A proper exhaust install depends on more than just the main components. Leaks at the header flange or midpipe connection rob you of performance and create noise under the hood. LCE Performance stocks exhaust gaskets and hardware specifically matched to FJ Cruiser fitments so you are not guessing on seal compatibility or bolt specs. Our Odds and Ends offerings include:

  • Exhaust gaskets sized for FJ Cruiser header and manifold connections.
  • Mounting hardware and clamps designed to fit OEM and aftermarket exhaust routing on 2007 to 2014 FJ Cruisers.

Having the right seals and fasteners on hand before you start keeps the build moving from the first bolt to the last weld.
