Finally found a Regular cab Chevy that was very well taken care of . 2006 model . Just got the wheels & tires , new lights & lowered the back 2" for easier short leg entry . Few more things & it'll be just right . Funny how a new or new to you vehicle can make you fell a little more like a kid...
Catalytic converter maybe ? Had a Chevy 1500 do that same thing on a trip to Florida . I cut the pipe on the side of the road & drove it back home . Was loud . but I made it . Crank it & let it run , Check the pipe to see if the exhaust is flowing freely .
Good Luck
.
Put Chevy emblems on it & hope for the best . jk
Do you want all show & factory go ? All go & factory show ? Or both .
Me personally I'd do as a sleeper . Leave the outside alone & make it fly .

Sounds like it could be the catalytic converter . If it's stopped up it can restrict airflow when it gets hot & put it back on the engine .
Happened to me on the way back from Panama city Fla . Took a hack saw , cut it off & drove home loud & proud . LOL .
