Headers, TTI or Doug’s?

I bought the TTI headers with the ceramic coating along with the rest of the exhaust including the slotted tips a few years ago already had a denso mini starter and fit perfectly on my 74 duster with a 360 right angled oil filter. Very high quality the muffler hangers are heavy duty and I used the stainless pipe clamps with a lock nut. When we were starting the install I was throwing the boxes away and my buddy said don't throw them away until we find out if this stuff fits and I crushed them and said I am 100 percent confident they will fit and they did... well worth the money look and sound great.
