If you have the time and a mock-up car and engine you should! With your own tools and experience, what's to loose. I got about $250 into parts,(just the headers & reducers) not including my welder and the power bill.LOL I see people spend a LOT of money on Doug's and TTI's...and they don't always fit. I would rather un-weld my homemade headers and make them fit than take a hammer to some new shiny TTI's.
