65 barracuda nightmare

I dunno I installed "Factory style" exhaust from Accurate, and I must say the sound takes a bit of getting used to after headers and 2.5 pipes out the back with Walker Dyno max...OP dont look at it as a "nightmare" its a learning experience...in the end it may cost you because Mopars aren't cheap. But the fellers here will help you out if you need parts post a wanted thread.
