When GM started installing V6 engines in Camaros and Firebirds, I was amazed at how completely WRONG they were with the exhaust tuning. Every one I heard sounded like a machine generating wimpy farts.
Couldn't ANYONE at GM think about tuning the stock exhausts so they sounded decent??? Ford didn't make that mistake with the Mustangs.
That's just another example of how thoroughly GM became clueless after the 70's. I was a GTO owner and drove some Chevys I really liked. But from 1980 on I can't think of a GM passenger car I found attractive other than the Corvette. TO my great disappointment, I thought the short-lived GTO replacement looked indistinguishable from a Chevy Cavalier.
I once checked a Pontiac 6000 series wagon out of the motor pool at Texas A&M and in less than 60 seconds I discovered that the entire instrument panel was hidden by blinding reflection from the dash below it, the oversized column mounted gearshift handle blocked my view of the radio so I had to bend over to the center of the car to see it, and when I popped the glove box, I found the door's lock was so large that it prevented me from getting a hand into the glove box without sliding over to the passenger side of the car. Disgusting, and every bit should have been caught before production.
