• Two Material Choices: Go T304 stainless steel for daily-driven toughness, or titanium for a lighter, more premium setup.
• Valved Control, Your Way: Choose OEM-style valve integration for factory-style operation, or the remote valve kit for instant open/close control on demand.
• Two Personalities in One Exhaust: Keep it civilized when you need to, then open the valves for a sharper, more aggressive tone.
• Flow-Focused Layout: Built to move exhaust gas efficiently for cleaner response and a stronger pull through the RPM range.
• Factory-Clean Fitment: Designed around OEM mounting points and alignment for a proper bolt-on install and a tidy look underneath.
• Built Like It Should Be: Precision TIG welding for strength, consistency, and long-term reliability.
• Install-Ready Setup: Everything needed for installation is included based on the variant you select (material + valve option).

The AZ Motorsport Valved Exhaust is built for enthusiasts who want a better tone and a more responsive feel without compromising fitment or reliability. It replaces the factory rear section with a higher flow design for a deeper, more aggressive sound and improved flow through the rev range.

Choose T304 stainless steel or titanium, and select OEM style valve integration or a remote valve system for on demand control. Clean welds, precise alignment, and real world durability are why drivers choose AZ Motorsport.

Flame Tune Note: For setups running big flames, we recommend stainless steel over titanium due to the higher heat load. Titanium is still a premium option—stainless is simply the better choice when you’re pushing extreme flame maps.
