One of the guys in my club, X77D80 (who posts here), has this on his Z and it sounds great! I think they also make a whole prefabbed kit around this muffler. If that's the case, I recommend using their kit. It will be a whole lot cheaper than fabbing up a kit to go with that muffler. Good luck! ~ John
Great muffler! I had the same type installed on my '69 Z28 awhile back, and I think it sounds very good. Driving down the road it doesn't run you out of the car and you can actually hear the radio, but when I stop at a red light I turn the radio down to hear the cam. The true sound comes out best while idling and going through the gears.
I've got the 80 series also. I used to have the 40 series on my last Camaro, so I can compare them directly.
I did like the sound of the 40 series, but was a bit loud for my ears for everyday use. Had a resonance in the cab at some RPMs, also. Nice stainless tips, easy to install.
I like the sound of the 80 series better. More of the 'tin' sound that I like. Little resonance in the cab. More efficient design due to the muffler placed farther back. Drawbacks: no exhaust tips, more difficult to install. However, it's more sturdy (both pipes are held in place by the muffler and h-pipe) so it wont move around any. The 'no exhaust tip' drawback may be good for some, so they may choose their own.
