1969 GM NOS Chambered Exhaust part #'s 3956749 LH , 3956750 RH.

In 1969 Many of the Big Block Chevelle SS 396 with HP ratings of 325, 350 or 375 came with these chambered mufflers from the factory also some of the 1969 COPO Chevelles with the 427 425 HP motor also received these.

The ones Peter has are a Left and Right unit. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img] I know because those used to be mine as i had 2 sets and sold one set to Peter a few years back.
Here is a photo of the other set i had which i put on my 1970 LS6 last year. They sound awesome [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Hear is how it sounds. Chambered Exhaust
