I put about 4' of pipe behind the muffler. The muffler is in the factory locatin. The funny thing is, When I built the exhaust, I did everything but the tail pipe behind the muffler simpily because I didn't have a mandrel bender. Before the tail pipe it was really loud but deep and rumbly. I took it to a muffler shop to install the tail pipe. Well when he started it up, at idle, it quieted down signifigantly. But the first romp of the gas served a big-o-bowl of Rice!

Exhaust sound comes in at about the 45sec mark.
