my friends 6.0 GTO has longtubes and sidepipes and that thing is soo loud is rediculous, he gets horrible gas mileage, and im pretty sure he bogs the engine down to keep it quiet

sounds like CRAP :thumbsdown:

It is a simple thing though.

horrible exhausts for horrible cars :roflpuke2:

The low rumble is nice until it gets up to the higher range. Maybe they should keep working on it to find a happy medium.
