I wish it were simply just strait pipes. The biggest buffoons are the ones running "pops and bang" tune where the clown car's engine dumps fuel into the exhaust to make it pop, bang and gurgle. Makes the car sound like shit but these mental midgets think it makes their already ugly slammed trashcar somehow sound cool. The kinds of people who do this usually have very little going on upstairs.

My dad bought a truck with aftermarket headers installed and dual aftermarket glasspack mufflers. If you were going down a hill and let off the throttle, it would "popcorn" like you described, but not obnoxiously. It was loud when you accelerate quickly, though. Scared a horse once when he pushed the clutch in and revved the engine.

I'd personally rather have a fast, but quiet vehicle. Most vehicles people make loud don't really have enough displacement to warrant that much sound so it's usually loud AND slow lol

That was also probably due to having a carburetor which won't completely stop putting fuel into the engine on decel like EFI.

I looked it up and the 1987-1991 Ford F series trucks came with some carbureted trucks and some EFI trucks, so it definitely could have been a carb helping too :)

old TBI-based EFI might not have stopped dumping fuel in decel either, haha.

You can (indirectly) blame World Rally for this. Those car started doing this 15 or so years ago - the engineers found that dumping raw fuel directly into the turbo (IIRC, they had a 5th injector in the exhaust manifold) kept it spooled up during shifts and throttle lifts.

injector antilag systems were around in the 80s, they are very hard on the turbos and manifolds however.

Yeah, I was thinking that the guys who are adding "anti-lag" to their street cars probably first encountered it watching WRC. Or maybe touring cars.

What's crazy to me is I hear it on cars that aren't even turbo - they're just running super rich with no muffler/resonator, so it pops/burbles more than normal. Can't be good for the car (the catalyst in particular, assuming they've bothered to keep it).

yeah the stupid "crackle pop" tunes are just deliberately running rich.

There's also "DSG farts" which actually have a performance benefit, but sound truly awful with aftermarket exhaust systems.
