There are butterfly valves in the mufflers that, in stock form, open at about 3,000 rpm allowing the exhaust to bypass the muffler.
This gives a small horsepower boost over the base exhaust, six horsepower.
With the valves closed it's as loud as a Cadillac.
I thought this was a performance car!
So I put a push switch in my dead pedal.
Now you can hear the 436hp of

ReplyDeleteMy friend Ace had a 6.0L Monaro, I mean "GTO" with Kooks, "cats," Corsa sport exhaust and a nasty cam (and other mods, 480 at the wheels). It would blow your ear drums out at full song on the outside. Nice on the inside, though. Then again, I've been rocking dumped exhaust on my truck long enough that I think I've caused hearing damage.
What? ;)
