what are the best full time mufflers .......
 

I need to lower the noise level of my 500 EFI's to meet the 90 decibal level. I have captains call with flappers on the transom right now and want to add tips or silencers to the transom to get within the limits. I've checked with Corsa and GGB and was quoted prices of $550-900 per motor. Does anyone out there have a less expensive option to get this done??

Not sure what you are looking for, Muffler tips maybe, Check out these Corsa's, I am not sure how many sets he has, But I bought a set that are on their way to me now.

Those are the smaller corsas and will restrict the 500EFI. I had those on before repowering to 500hps and weht with CMI muffler tips.

Had a buddy gut the smaller corsa with a plasma cutter and I don't see how exhaust found it's way out.

OK, wasnt sure what you were lookin for, I should read the 500!!!

Well, thats kinda what I am lookin for, just a Small block with thru-hulls, and it was gettin a little annoying in the MANATEE zones!!!!!

I've been told the smaller corsas are for the small blocks and the bigger corsas are for the big blocks. Those on ebay should work for you rchevelle71
