Has anyone used Stainless Marine exhaust on a 600/700 staggard boat???

I used the Gen III system on my staggered top gun raceboat, 598 inch, 1150 hp motors. They worked better than the Stellings, more power and more torque. Ask Tommy at Chief, he ran tests on the dyno to prove the difference. I was extremely happy with them.

they will hold up much better and last longer than the headers too, and are much less coin... its a no brainer

I can't run Gen lll's on Mercury 600sci because of the coolant tank clearance. They need to be Stainless Marines conversion kit

cant you relocate the tank, or hit it with a hammer for clearance, flintstone's style
