Stainless Steel Cat Back Exhaust Systems

Install an Ultrex Performance cat back exhaust and unlock the power and sound of your car. A cat back exhaust is an easy straight bolt on, so you can DIY or have your preferred workshop install the exhaust system for you.

All our systems are crafted exclusively from stainless steel, with full mandrel bends to optimise power. They are TIG welded for a high-quality finish.
