exhaust

Hit Craigslist and try to find a solid, used Flowmaster. I've got a 2.25 inch in and out on my 64 170 daily driver and it sounds perfect! Rumbles like an 8 at idle and low speeds, screams like a banshee when you spin it to valve float.
Muffler is mounted in stock location with just a short turndown in front of the axle.
Should be able to find one in the $20-30 range.
