Turbochargers muffle an engine nicely!
I saw a dude on the Power Tour a while back...red late-80's (last year with no airbag...1989?) Firebird Formula, Dade County, Florida plates, it looked like a stocker with chrome exhaust tips & nice wheels. Stock interior, stock (auto) shifter, no aftermarket gauges...but wait, that's a rollcage tube next to the A-pillar!
It ran 9's on E85, powered by a twin-turbo, intercooled LS1.
