Well the body and paint work is finally finished on the WarPig. Rear suspension rebuilt(with new Sullybilt plates of course). Bogie pin and bushing kit(Applied). Rebuilt house windows with powder coated frames and new rubber(Alex Sirum for all window hardware). Rebuilt high efficiency dimpled core radiator(Seattle Radiator). New transmission lines. New roof vent covers and bathroom fan assembly(Alex Sirum). New led clearance lights(Alex Sirum). Stainless reproduction T handle latch assemblies for hoods and rear compartments(Alex Sirum). Led tail lamp bulbs(Alex Sirum). Patterson distributor with Howell E.F.I. and EBL <not yet installed>(Applied).

Next on the list will be replacement of the decrepit exhaust system and install bung for o2 sensor. Engine is a fairly fresh 455 with headers of unknown make. Currently the headers dump into a large resonator type thing under the house floor directly behind the cock pit step then dumping into one 3" pipe which runs through the cross members and out the back of the coach(passenger side). I have read on here that the "ideal" set up is one muffler toward the rear of the coach. I have very little room toward the rear due to placement of black and grey water tanks then further back, the hitch. I had a friend from a mechanical/exhaust business nearby stop by and look under the coach to see if he would be able to hook me up. He was in agreement with me that insufficient space exists in the rear for a muffler and was concerned about placing a two into one muffler where the resonator type thing is due to the extreme heat from being so close to the engine(his initial thought was to use a Camaro style muffler which would work well perpendicular to pipes coming off the headers but seemed worried about frequent replacement due to heat). So, who can suggest options or maybe links to some photos of systems which have been successful??

Thanks!

FWIW, this is what I did on our 78 Royale with Grey and Black water tanks.

I kinda built the system myself, but if I had it to do over, I'd just buy the kit from Jimmy K and be done with it. JMHO
