Dana Marine Products, has assembled the best after market exhaust system for
MerCruiser 496 engines. Kit includes a set of specially internally runnered
header style manifolds, with all stainless steel tube style risers. This is a direct
MerCruiser replacement for 496 Mag and HO engines. Includes all mounting
hardware and brackets. On twin engine units you will need no less than 36.5" on
center as these are 1-1/4" wider. This set up adds approximately 40-45 true Dyno
HP  & approximately  50-55ftlbs of torque to 496 Mag and 496 Mag HO. This is a
great upgrade over stock and half the cost of headers. In fact they out performed
most header in dyno tests.

You have to love this.


I'll be posting more detailed information on this subject tomorrow. Many of you have probably seen them at the show. We have the new video of the
dyno work and boat install playing in our booth as well as Eliminator's. (we used the new 22 Daytona for the install) The boat at the show is the one we
ran. I've seen alot of nice comments about the looks of that boat, but let me say first hand, that boat runs awesome. It loves to run fast. That boat right
now will cruise at 66 mph at 3500 rpm. And it's smooth as glass. We ran top speed at 83 mph, stock was 77 mph.

I'd also like to publically thank the following people,
Ray and Larry from Raylar Engines, these guys are in it to win it. They donated 4 full days at absolutely no charge to help us get this project off the
ground. They also had alot of input on the initial developement of the kit. Top notch people, that are truly into providing high quality products.

John West and Mike Harland from Ultra Custom Boats, these guys let us use three brand new 496 engines for both the dyno work and our display
engine that we have at the LA Boat Show. John's always up for cool projects and his generosity allowed us to complete the project on time. Without the
engines, we'd still be sitting in square one.

Bob Leach from Eliminator Boats, One of the nicest down to earth guys I've ever met. Bob didn't hesitate for a minute at our request to use his brand
new boat. The 22 Daytona was a perfect boat for our water testing.

Paul and Kirk from Extreme Custom Marine, Paul was brave enough to go boating with me in 30 degree weather and wide open throttle. Paul's
extensive knowledge of the Mercruiser 496 was very helpful in our completion of this kit. He personally performed the engine diagnostics including
portable exhaust temperature readings to insure against any lean conditions. Being within a few minutes of lake Elsinore, Paul ran down to help us out
several times. Again, without his help, we'd still be trying to figure things out.

I think it's important for everyone to know that Dana Marine Products received alot of help on this project. We didn't just throw some half ass exhaust
kit together. The guys that I mentioned are true professionals and are a huge asset to the marine industry. Thanks again guys!
