Weapon-R 953-300-102 3-Inch Stainless Steel Turbo O2 Housing & Downpipe Kit

The Weapon-R 953-300-102 is a high-performance 3-inch stainless steel turbo O2 housing and downpipe kit designed to replace the restrictive factory unit with a significantly larger, free-flowing alternative. Purpose-built for performance-minded enthusiasts, this downpipe is among the largest diameter options available in its class.

Key Features:

• 3-inch diameter — substantially larger than the OEM downpipe for improved exhaust flow and reduced backpressure
• 304 stainless steel construction — resists corrosion and withstands high exhaust temperatures
• CNC mandrel-bent tubing — maintains consistent inner diameter through all bends and is designed to clear factory lower arm bars without modification
• TIG welded joints — strong, clean welds throughout for long-term durability
• CNC-machined flanges — precision-machined mating surfaces ensure a proper, leak-free seal at all connection points
• Includes O2 housing for complete turbo-back downpipe installation

The Weapon-R 953-300-102 downpipe and O2 housing kit is a direct upgrade over the factory unit, delivering improved turbo spool and exhaust scavenging for increased performance. Built with race-grade materials and manufacturing processes, it is equally suited for street driving and track use.
