Re: Muffler question
There's a test somewhere here on the net where some well known Poncho racers tested a slew of exhaust setups on a Pontiac bracket wagon...I can't find the link (yet), but a Dynomax w/x-pipe combo was just a shade behind the open header combo...
EDIT: here's the test...a good read for everyone: exhaust shootout
