I'm seriously thinking of buying new exhaust for my
stock 502 mags. I know there has been several threads on exhaust,but has anyone used the Rev marine manifolds? If so,any results would be great.

PM Gordo he sells and installs RM

A Fellow boater and board member is in the process of an install right now. I'm sure he will post the results as soon as the boat hits the water.

I'm putting a couple of pair on now. They look just like and are a copy(I think) of the Gil or Merc HP exhaust. I expect the same performance. QC may be a little less but WOW for the diff in $ I'd order these again and the customer support guy Wade is great.Hoping for 10 % gain but also added dart intake (then I'll connect my M3's and see what happens

Cool, thanks,keep me posted on the results. Anybody
else with info?

I have installed a pair of them, the owner of the boat said he noticed a gain and was happy with the modification. I have found that getting the right relocation brackets is the key to making the install go smoothly.

I heard a 4 mph increase in a 33 Outlaw w/ 502's. The install included aftermarket flame arrestors and an increase in prop size.

I am very happy with the set that I installed. Before the exhaust, 65 was all I could get. Now, with a labbed prop and the exhaust, have seen 69 on GPS. Very happy with the exhaust!!!

I just installed a pair on my 22' Donzi classic last weekend and am very happy. Like was stated you need to make sure you have a bracket to relocate the steering pump, Oil filter and fuel filter or pre-fab one like I did. I picked up almost 300 RPM with nothing else new so I am very happy. There are some pictures of the install on my website if you want too look. They are under the picture of my Donzi at - tiemworks.c0m -

So far, nothing but good. Anyone have any reason
not to by the revs and go with somthing else.
Stainless,Imco, emi thunder? I sure like the price
of the revs. I intend to keep my engines pretty
much stock (502 mags). 525 h-p tops when I
have to rebuid.
