620-32570 Cyclone Water Jacketed Header System For GM LS and Standard Dimension Bravo - Fully Polished - Pair of Headers for one engine.
This new cyclone header system is designed specifically for GM LS engines. The tailpipes are set up for standard Bravo exit locations.
This Cyclone wet exhaust series header works perfectly on both
stock and modified performance applications This header mixes
engine cooling water with the exhaust near the end of the tailpipe That
allows you to use a 4" rubber hose connection to attach your transom
mounted exhaust tips This is the perfect replacement for your factory
exhaust system. Gaskets, and bolts
included.
If you are one of thousands of performance boaters oseeking the power and styling from stainless
steel tubular headers then you're looking at the leader in exhaust technology These "Cyclone"
header systems share 100% 316L stainless steel construction. All appropriate flanges are laser cut and
CNC machined for a perfect gasket seal. Each individual exhaust tube is bent to precise, exact
tolerances every time. A computer designed fully welded water inlet manifold provides equal water distribution
to each exhaust runner tube. While each set of headers goes through a 1900 degree annealing
process that multiplies the durability factor of the header many times over while providing added
protection against corrosion. But the heart of these systems lies in the ability to generate loads of
additional power. By using CAD-5 Technology to develop a unique staggered tube runner length, these
systems are capable of maximizing the broadest low end and midrange torque, all the while yielding
incredible peak power gains. These systems are available in many configurations to fit every boaters needs.
Rest assured when you lay down your hard earned money because the system comes complete with
all necessary mounting bolts, gaskets, and shift and oil filter brackets making installation a snap. This kit includes one (1) O2 bung standard, if you need a 2nd O2 bung on your kit, see related parts below.
