Modifying stock "sandwich plate" 3cyl exhaust
First i would like to say thanks for all the good info that has been posted at this forum :)
I have learned alot about the differenses about the 3cyl OMC engine.
To the question:
I have the -76 version of the 3cyl Johnson Stinger.
Is there anything to do to to gain som RPM and performance with modifying the stock "sandwich plate" exhaust on this engine?
I know that there is available different MOD exhaust (hustler, nydahl ) to bolt on for this for the real performance but they seem to not be available that easy :(
In this topics it is stated that cutting the "bridge" between nr 2. and 3. cylinder you can gain som RPM. Does this really help?
