KSH LT Header & X-Pipe (Kooks Part: 2311H430)
If you want to unlock serious power from your supercharged Cadillac LSA engine, swapping out those tight factory manifolds for the KSH LT Header & X-Pipe (Kooks Part: 2311H430) is easily one of the best upgrades you can do. The stock setup on these cars chokes the supercharger down way too much. Upgrading to the KSH LT Header & X-Pipe (Kooks Part: 2311H430) lets those hot exhaust gases escape fast, dropping your boost stack-up and giving you an instant jump in horsepower.We tell our customers to go with the KSH LT Header & X-Pipe (Kooks Part: 2311H430) because it pairs high-flowing 1-7/8 inch headers with a massive 3-inch stainless steel X-pipe. Plus, this whole setup features Kooks' specialty Green catalytic converters, so you don't have to worry about melting your cats when pushing high boost on a modified forced-induction engine.Features and Benefits

FAQ
Do I need a custom tune right after installing the KSH LT Header & X-Pipe (Kooks Part: 2311H430)?
Yes, you definitely do. Changing out factory manifolds for long tubes moves a ton more air through the engine. You will need a custom ECU tune to get the most power out of it and keep the check engine light from popping up on your dash.Why are the Green cats in this kit better than cheap high-flow cats?
Standard high-flow catalytic converters melt or fall apart quickly under the massive heat and pressure of a supercharged 6.2L engine. The specialty cats built into the KSH LT Header & X-Pipe (Kooks Part: 2311H430) are engineered directly for high-horsepower racing applications so they won't degrade inside.Are O2 sensor extensions included in the box?
Yes, they are. Since long tube headers move the collector location further back under the car body, your stock wiring won't reach. The kit includes the necessary extension harnesses and the core mounting hardware to bolt the flanges straight to your cylinder heads.Related products
