Default 496HO Exhaust Mods
Besides removing the turbulator/restrictor plates are there any other mods that can improve the performance of the stock Mercruiser/Gil exhaust system?

Other than removing silencers in the tips (if equipped), none that I am currently aware of..

You'll need to speak with Ray at Raylar. There is some general cleaning up (grinding) in some areas.
Evaluex, do have CMIs on your Nordic?
