my Low dollar 318 hop-up project

the exhaust is being a pain, but I'll get it. I ordered the TTI head pipes and I ordered the Jegs header back dual exhaust kit thinking I'd do it myself. The head pipes from TTI fit like a glove and end at the cross member, but the Jegs kit isn't liking the car :(
As mentioned in the 2nd post of this thread, this build is assumed a person already has a car with the 318 in it and dual exhaust.
