Torque Solution Titanium Top Mount Charge Pipe is a great addition to your engine bay! This kit replaces the restrictive OEM plastic corrugated charge pipe with a beautifully crafted titanium charge pipe, CNC billet aluminum turbo adapter, 4-ply silicone hose couplers and silicone safe stainless steel worm gear clamps. The turbo adapter converts the turbo outlet to 2.25" and the charge pipe is 2.25" at the turbo and smoothly transitions to 2.75" at the top mount intercooler. This results in overall improved flow, throttle response, efficiency, and of course increased horsepower all on the factory tune. No tune is required, but of course greater gains can be had with a tune.
