still looking for EMI Thunder For Bravo app
 

Looking for a good used set of EMI thunder Manifolds and Performance tails.

Anyone parting with one set that are in good condition.

Pm me if you have.

They are pretty affordable through Revolution Marine. Same manifold, made at the same foundry. We dont sell their exhaust anymore, its a price issue, not quality issue. Many satisfied customers.

Thanks I will keep that in mind :drink:

But looking for a good used set.. less $$$ :ernaehrung004:

Thanks for the post.. I went on their site, going to do some research on them. the price seems right for sure.

Also going to look at the engine pre-oil system.

I am not sure if the revolution Marine system will be ok with a 600 hp 502 application. Reversion ?

anyone running these, wonder how they sound?

Howitzers
 

The earlier Revolutions had a cast riser which I am certain will allow reversion on as hot a cam as you would need for a 600HP 502. However I understand that they (partnered with Eddie Marine, are now making a fabricated stainless riser like the IMCOs. That should better. But still that will probably allow reversion with that hot a cam, depending on the idle speed. IMCO makes a Powerflow PLUS which has individual runners that pass through the cast riser. 32 inch primary runners as I recall. With a decent length Dbl wall tail piece, that system should not allow reversion on your engine...
Good Luck.
