Who made this exhaust? Any info?

MILD THUNDER

Could those be the very early Gil manifolds?

There has to be someone out there that knows what these are. Could they be Pattersons?

These were made under several names including "lighning" later the KE company sold these until they came up with the most recent cast design several years ago.

We used these for two years on a pair 1200 hp SC engines - they worked great - never had an issue - do you need a fresh pair with wleded on 3/4" water jacket opening ?

THESE PICTURES ARE THE OLD LIGHTNING PERFORMANCE PRODUCTS OFFSHORE EXHAUST SYSTEM, THIS WAS BACK IN THE LATE 80'S WHEN KEITH EICKERT WAS THERE. THIS MANIFOLDS WAS A GREAT MANIFOLD THE BOLT PATTERN ON TOP WAS A DOMTA. CARB BOLT PATTERN. THEY WERE 34.5" WIDE ON A STD DECK BLOCK WITH CAST IRON GM HEADS AND AROUND 25" HIGH , THESE WOULD NOT FIT IN A DUAL ENGINE, ONLY STAGGER OR CAT BOATS. LIGHTNING CHANGED ITS NAME TO TORQUE ENGINEERING WHEN KEITH LEFT THE COMPANY.


Also do a search on the forum for Drake headers or exhaust and you will find a few other threads with some more info. Supposed to work awesome, there just not made anymore.

Actually, they will fit twins if the center to center distance is 34.5" or more. I had them on my Black Thunder at 35.5. 35.5 is a common distance on large twin engine boats.

Thanks for the info everyone. And yes Mr. P is correct these came off a side by side.
