Which replacement system should I choose for my totally stock 1996 502 Magnum MPI GenVI with Mercruiser's Silent Choice system which I want to keep in a 22 Donzi Classic in fresh water with stock Bravo 1 drive and 25" MiragePlus prop.

Both kits supposedly come with all necessary brackets and in "Silent Choice" versions.

My priorites/concerns are ease of installation, performance, reliability.

I have heard the installation of the Gil Magnum Choice system requires some work to get it to fit.

Any comments greatly appreciated.

Thanks

i've seen alot of problems with the Gils. Stainless Marine is a quality product with great service and factory support.

Contact Too Old for the best price.

Ive been using and have installed Gils for years. Never had a problem and they work well. Cant compare them to the SM since Ive never used them.

Based on what I have seen over the years I would prefer the Stainless Marine exhaust system over the GIL's.

Stainless. Had a set of gils fail.

I have a '93 Baja Islander that I put a 95 502 EFI in. It had Corsa silent choice with the stock 7.4 when I got the rig. After I had it all up and running with the 502 and stock cast iron exhaust manifolds I put a used set of Gil mags in and no problems for 2 seasons. Have fun. ttfn

Have you checked into the revolution marine exhaust? I'm pretty sure they make a set for silent choice.

Stainless Marine makes more power than any... Tested them all in the dyno, the Gen 3 made 30 horses more than the CMI in a 540. Stainless Marine has allot of years of expertise.

Here is a breakdown for CMI Tube Top, CMI Elbow Top, Stellings, Eickert, IMCO Powerflow, Gils, Stainless Marine v1, v2, Merc 500HPEngine in Excell that has different comparisons.
