Terry, The mufflers are in front of the X-frame & the resonators are behind the X-frame. The purpose of the resonators is to prevent certain sound waves from the exhaust that would resonate throughout the car at certains engine RPM's if only mufflers were used. Anyone owning a Corvette with an aftermarket exhaust will know what I mean.

I think it came with 2 inch pipes and two mufflers and two resonators. Were the mufflers ahead of the X-frame and the resonators behind the X-frame? And were the resonators just additional mufflers, or were they something special? Thanks in advance for your help. Terry McTaggart, Dayton Ohio, 45 miles north of Cincinnati.
