Pops and bangs please?

Spray a bunch of lighter fluid in the exhaust, the whole can. That should work.

newer vehicles are able to do it via tune (and some stock) due to variable cam timing, which these trucks don't have.

It's been a bit of a craze here in the UK. Where I live on an A-road (60mph speed limit) they accelerate only as much as required to be able to lift off the throttle and have it banging like a ********* door in a gale. Call that driving? I get the feeling they're actually scared to stay on the throttle pedal.

Never got why the crackle exhaust was a fad. In the Harley world, an un-tuned EFI bike will crackle with straight pipes on decel, sounds like sht. A tuned bike will rap almost as loud as running WOT on decel, sounds badas!.

Manual transmission and a cam should do it.
