CHAMBERED EXHAUST (THE MYSTIQUE):
WHAT IS CHAMBERED EXHAUST?
Early OEM chambered exhaust systems appeared on various GM musclecars back in the 1960's. Sidepipe-equipped Corvettes used them, and chambered exhaust was available as an option on '69 Z-28 Camaros, & '69 Chevelle SS & big block Camaros. Olds 442's also incorporated a chambered section in the tailpipes after the oval mufflers for additional sound tuning & noise reduction. Chrysler had originally planned to utilize chambered exhaust on AAR Cudas & T/A Challengers - but for whatever reason, the finished products ended-up with a very restrictive (175 cfm per muffler) side exit exhaust with oval mufflers. Basically, a chambered exhaust muffler looked like a swollen section of pipe with "dents" in it. Inside the muffler, was a louvered core or flow tube, which reduced in diameter & restricted flow because of squeezing down the size of the path - this was a negative. As exhaust passed through this section, sound waves escaped the flow path & into the outer cavity - this is where the "dents" or "crimps" performed their magic! A unique turbulence was created in the sound waves, uninhibited by any packing material (there's no fiberglass or packing to burn-out). The crimps textured or "tuned" the sound in a way unlike other more conventional mufflers or glasspacks - vehicles running chambered exhaust had a sound all their own! Glasspacks contain packing material which absorb sound, & they generally produce a smooth tone. They also very often have a smaller diameter flowpath than the entry/exit of the muffler - this affects cfm flow capabilities negatively. A smaller flowpath also produces a quieter exhaust note.

I've never seen a 68 442 with them so I can't even tell you for sure

Karl was working on making a set for a '68 H/O. I believe that he was working with Inline Tube ( I can't remember for sure) to produce these. I haven't seen any updates in awhile over on the FB Olds forums.

The Pypes have the 2 1/4" flange then into a 2 1/2" pipe. Their fit has been anything but consistent on their pipes. Ram Air Restorations makes true 2.5" mandrel bent down pipes, saw an installed pic on here, looked really nice, aluminized not stainless. Also made for manifolds or Thornton's shorty headers. Do you want an X or H pipe, also changes the sound. The Hooker Aerochamber mufflers sound awesome but are on the loud side. The Dynomax Super Turbo are noticeable but not loud. Of course muffler placement and interior padding also make a difference. I have those 2.5" Pypes tips, their name is etched in and are good quality. I don't have the cut out bumper so I can't say on how they fit that.
