Just got my coated and polished headers from TTI for my Hellcat swapped Barracuda. These things are fantastic! We gave TTI the engine size, transmission (4L80), front suspension {Alterkation} and starter on the passenger side info and they sent me the best fitting headers I've ever installed. I was blown away by the quality. I highly recommend TTI if you are doing a Gen III swap.

They are very good, I wish I had known they had Borgeson box specific headers though. I bought mine second hand and they were for a standard box. The #1 tube needed quite a bit of adjustment.
