I'm sure this question has been asked a bunch, but I'm installing thru hull on a boat that doesn't currently have it. I want to run tips with internal flaps. I'm concerned about rattling at idle. Looking at hardin, Eddie marine, and Rex marine. Really leaning towards Rex. These will be going on stock 454mag MPIs. What's everyone's thoughts? Thanks

I have the Eddie Marine ones and like them fine...no 'rattle' at idle...just kind of the 'whoom whoom whoom whoom' deep burble.

Thanks for the input

Corsa by far.
