Cyclone "BIG GUN" System For GM Big Block - Fully Polished

At last the Biggest and the Best System available for the ultimate in performance These systems use an actual 4" internal pipe with a massive 4-1/2" outer shell These systems produce almost non-existent restriction to exhaust flow through the double wall water jacketed transom tail section These systems are referenced as dry tailpipe due to the fact exhaust flow never makes contact with the discharged water Each of these systems are designed for large cubic inch high horsepower and supercharged applications Additional transom sealing rings will need to be purchased separately When only the best will do Cyclone delivers Note: all Big Gun riser/tailpipes are custom built, a simple measurement guide is all that's needed to complete Allow 7-14 working days to build.

If you are one of thousands of performance boaters seeking 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 mid range 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 and gaskets making installation a snap.

Cyclone 4.50" "BIG GUN" Below Platform System For GM Big Block - Fully Polished

Description: For those high horsepower supercharged engine applications that require an exhaust exit that's basically 12" lower than a standard Bravo application. These systems feature a 4.-1/2" external pipe with a 4" internal pipe. These systems produce almost non-existent restriction to exhaust flow through the double wall water jacketed transom tail section. These systems are referenced as dry tailpipe due to the fact exhaust flow never makes contact with the discharged water. These systems are VERY LOUD due to unrestricted exhaust flow. Additional transom sealing rings will need to be purchased separately When only the best will do Cyclone delivers Note: all Big Gun riser/tailpipes are custom built, this price is based on the system referenced above. Changes or modifications could cost more. A simple measurement guide is all that's needed to complete Allow 7-14 working days to build.

Cyclone Dry System For GM Big Block Custom Dimension Dry System - Fully Polished

For those of you seeking the ultimate performance from your large cubic inch, aggressively cammed, naturally aspirated or supercharged engines This double-walled tailpipe discharges all of its cooling water through a 3/4" NPT bung in the side of the tailpipe It keeps the exhaust gas from coming in contact with any discharged water These tailpipes extend through the transom and require the additional purchase of transom sealing rings.
