This complete header kit makes huge increases in power output of your 5.7L Toyota. Tri-Y (or 4 into 2 into 1) style headers by design will increase the power of your motor across the widest RPM band possible. That is the beauty of the design and that is why they are the best street header available. This kit includes ceramic coated long tube tri-y headers and adapters to connect the headers to your factory y-pipe. To make these headers last, we built them using industry leading 14-gauge steel tubing with 3/8" thick flanges. Topping all of that off, our headers come beautifully ceramic coated to greatly reduce under-hood temperatures and protect them from the environment. All 100% American made, and backed by our lifetime warranty. Install these long tube headers today and feel your vehicle's true power potential!
