New Exhaust for my Duster?

Sounds like you got the cut-outs so you can un-cork your exhaust in front of the mufflers. Usually that's something you do at the track and there is no muffler or anything hooked up to it. Just open 'er up and let 'er roar. Flex-pipe won't last long ( at all!) Your better off picking the right little bends and pieces and clamping it up til you can save some coin to get something better.
