Kooks 05-06 Pontiac GTO LS2 6.0L 3in x 3in OEM Cat SS Exhaust Conn. Pipes

If you're looking to get more out of your 2005 or 2006 Pontiac GTO's LS2 engine, these 3-inch stainless steel catted connection pipes from Kooks Headers are a solid choice. They replace the factory pipes, helping your exhaust system breathe a little easier and potentially unlock some extra power. These are designed to connect to the factory catalytic converters, making them a good option if you want to upgrade your exhaust without going fully catless.

Kooks builds these pipes using T304 aircraft-quality stainless steel, which is known for its strength and resistance to corrosion, so they should hold up well over time. They're handcrafted in the USA, a detail Kooks has been proud of for generations. These pipes feature standard race cats, which are designed for maximum power but are not intended for use with forced induction setups like superchargers or turbochargers. If you're running a naturally aspirated LS2 and want a bit more exhaust flow, these are worth considering.

When installing these, remember they are designed to connect to your OEM catalytic converters. If you're unsure about the installation process or what else might be needed for your specific setup, it's always a good idea to consult your service manual or a trusted mechanic.
