TTI Shorty Headers

The shorties don't save as much space as people think. The headers themselves offer a little better clearance, but the head pipes are just as tight in a lot of places as a set of long tubes.

I have Doug's D453's on my Duster with a 340. I decided I was going to swap them out for TTI shorties to gain some ground clearance and a better fit, but after going most of the way through the install I decided the TTI's caused just as many new clearance issues as they solved, particularly at the oil filter with my set up. I put the Doug's back on, and the only clearance dimples they needed were at my 1.12" torsion bars.

I did a write up on the swap and my findings in my build thread here My "new" '74 Duster- or why I need a project like a hole in the head

So, my .02 is that the shorties will give you better flow than a set of manifolds, but they're really not much less of a headache to install than a set of Doug's long tubes. At least on my car anyway, as always not all of these cars are identical and especially with headers a few small body tolerance differences can make a big difference. But for me the clearance issues that the TTI's solved and the different clearance issues they created compared to the Doug's were about equal.
