Hi,
I was checking out some exhaust specs at
formatting link
and I noticed that the cop car 5.7 liter exhaust uses a 2 inch tailpipe and muffler.
But the smaller 5 liter engine uses a 2 1/4 inch tailpie and a 2 1/2 inch muffler.
Why the heck would they decrease the exhaust size for a larger engine ???
Thanks, L
