Has anybody installed the Eddie Marine Thumpers with Silent Choice elbows. I bought a set and was going to tackle the job myself. Any tips? I have a Fountain 32 Fever with twin 502 mag mpi. Not a whole lot of room in the engine compartment.

Imco makes the Thumpers

Ok, I mean the Eddie Marine exhaust with chrome elbows. I also was looking at the Thumpers before I purchased these from Too Old.

I installed the EMI thunder manifolds with the short stainless risers for cap. call[corsa]on my baja 29 outlaw with twin 454mag mpi's, do yourself one big favor and call IMCO and buy the longer oval hoses that go from the bottom Y pipe up to the silent choice divertor, the stock hoses or not really long enough, you could use them but you would not have much hose on each end of the pipe[also that is near the water line] for the double clamps, the new hose from IMCO also has new stainless clamps, make sure you also get the plates and angle brackets to hook up your shifter, computer box and oil filter bracket[my engines are VST] also the high pressure power steering hose on the back of the pump will hit the manifold by a small amount[ I put more of a bend in the stock hose to clear]also make sure you retorque the manifolds after you run it a few hours, they torque to 35 ft. lbs.
