I worked in the end of the industry where the rubber hits the road. The end
user of automotive products couldn't have cared less about UHC, CO, NOX, or
any other three letter substitute excuse for the performance that they used
to enjoy. They didn't want technical explanations, their only interest was
in 0 to 60 times, smooth idle, no stalling when you stepped on the gas and
unimportant stuff like that. Zone managers, technical support people who
worked for the big 3, were busy covering their exposed rear ends with fancy
excuses, and left techs like me to deal with irate customers who were
getting 16 to 18 mpg with their 50's and 60's cars, only to buy the 70's
and 60's cars that got 9 to 12 mpg and wouldn't pull the hat off your head.
Wouldn't go back to that era for any amount of money.
Your experiences may vary a bit.

Darn cell phone. Should read 70's and 80's.

The rumor was - and I buy it - the Mazda engineers spent many hours listening to the MG A and B, and tuning the Miata to duplicate the sound. On the four cylinder Miata at least, they hit it pretty much spot on. Their success may well have led to the noted foolishness.
When someone makes a muscle car which sounds like a 440 spinning over and starting, I'll consider buying it!

How 'bout a muscle car that will blow the doors off of everything else on
the road with only the sound and smell of burning rubber? That would sound
better to me! :-)

My old trucks have sound modification technology on them. It's called headers and Cherry Bomb glass packs. I always liked their Motto "Cherry Bomb - Disturbing the Peace since 1968". Seems fitting for my 1968 and 1969 trucks.
On two cars I have gone with "Flow Master". Really good sound, particularly the bark at idle and the full sound at high RPM shifts.
I'm not sure what to do with the GMC, I would like a little noise but not obnoxious. I put mild performance mufflers on my Northstar powered Cadillac Deville and I think it is a nice compromise for a luxury car. Just the right amount of sound when you get on it but quiet under mild acceleration.

Jim,
Our memories are a lot alike, but mine had hard data as a background.
In the closed discussions of the Michigan automotive community, there was a lot of strange talk. First issue was that the original EPA were all in exhaust composition as percent of concentration. (They didn't yet have dilution tunnels so grams per mile wasn't even possible - yet.) So, go with a big engine and tune it for minimum smoke.
One of the great jokes on the car buying public was that the best way to meet the standards was to take a good engine and make it run like crap. All three manufactures had to go to catalysts by late '70s. One of the good ways to make them work was to setup a V-engine so one bank ran rich and the other ran lean. The cat would stay lit across a wide range and O2 sensor would average what it saw and keep it running. These were the low teens (MPG) Novas and Fairlanes.
I to am glad that era has passed.

If the GMCMH never used EGR, why are we discussing it here? You could massage the timing and mixture for best power and mileage, which usually means lowest emissions. The canister is a win win and should never be bypassed. Engines (powertrains) factory tuned with EGR will have problems if defeated including detonation and trans burn out from soft shift slippage. EGR is out if circuit at idle and heavy throttle anyway. There I go talking about EGR again.

If it had the CA emmissions package it will be listed on the build sticker in the glove compartment.

The Miata was designed and built in Hiroshima Japan. The lead planner was Bob Hall, twin brother to my then planner Jim Hall who you see on TV all the time. The designer was Mark Jordan--son of the famous GM designer Chuck Jordan. To my knowledge, the Miata was never built in the US. However, the stories of the exhaust tuning are correct. Jim, Bob and myself spent a week in the wine country of California evaluating one of the first prototypes.

Along those lines, a local production house a friend runs roughed a spot on spec for Year One. It was a takeoff on the then current Pontiac ad with the two cars doing a stoplight drag. The Pontiac comes to the light and stops. The camera pans to the light, and it's an old style tree counting down to green, while you hear a Mopar starter spin off something making a lot of racket and a noisy high speed idle. Comes the green and the shot is a large explosion and cloud of smoke under the light. As it clears, the doors fall off the Pontiac and rattle on the ground in the disappearing smoke. The camera pans down the street and zooms on a RoadRunner idling off the exit lane of what what has become a strip, and the Year One logo and motto fade up onscreen:
"DON'T CRUSH 'EM, RESTORE 'EM"
They didn't buy it for whatever reason so it never got past a rough storyboard. I think they'd of sold some parts with it, but it probably would of urinated CPC division off to the nines.
