Non-FE Discussion Forum / Re: Engine Masters David Freiburger compares 2-1/2" to 3" exhaust
« on: May 23, 2016, 09:01:48 PM »
On two occasions of running 2.5-in pipes through approximately stock under-chassis routing and tailpipe exit locations (in an 80 El Camino and a 67 Cyclone) the fit was VERY tight, especially going over the axle tubes and out the back. I imagine with 3-in tube it would be a first-class exercise in frustration. But Freiburger's zip-tie philosophy is not in the least bounded by such old-fashioned constraints.
As someone who messed with more than his fair share of thrashed muscle cars back in the day, I can't think of many -- if any at all -- that had pipes bigger than two and a quarter inch diameter. But they weren't making 600 hp either, most realistically only about half to two thirds that amount.
