Doug's exhaust help '66 Dart

I looked into the tti's but there website said that I would have to notch by transmission cross member, and buy some special mini starter that cost a couple hundred bucks. That's the main reason i decided to go with the Doug's.
66dartman, as of now im still saving up for the doug's but should have the cash all together by the middle of april. How much are you wanting for em?
