I like the sound of this one on the road a bit better (than static idling).. :)

Is there any difference in sound of the chambered system due to the solid lifter cam of the Z vs. the hydraulic of the BB cars?

The L78 is a solid lifter engine too.

You are right. I was asking about the L34 and L35 more specifically.

The indicated redlines are higher on the solid lifter engines, and the 'actual' redlines are higher yet.. :)..   So if you are asking if they *sound differently* at redline...   yes..  :) ..

'Red69' and I worked out a deal, so that he received my NOS chambered pipes, and I got something I needed for my late '69 Z28 (a very nice pair of GM resonators which late Z-cars received).   And the shipping worked great too, between Bama and Wash state, which is a marvel in itself!... :)   Since my original exhaust pipes were cut for headers, I need to find a good original pair of head pipes and I'd be set with all-factory original GM exhaust...  :)

PS.  Reading this old thread, someone asked why the '69 Camaro chambered exhaust had so much trouble meeting noise standards (in PA and maybe elsewhere?), whereas the mid year Corvettes seemed not to have as much problem and they use the same muffling technology.   I'd never considered that before, but  *Maybe* it had to do with the single point decibel meters, and both Camaro exhaust pipes coming out the rear, and the corvette having side exhaust (you really don't get the full effect from a single side or the back)...
