Doug's or TTI headers

I will say the TTI's are a bit harder to install over the dougs d450. On my 65 Cuda I'm running TTI's I had to mount my brake prop valve on the master with a bracket as there was no room to frame mount it. I used a Robbmc starter for more clearance and there is 2" of room from the header to the starter and it could be removed without loosening the header. I'm also using big block torsion bars and had to make a dimple in one tube as when the engine ran it moved around a bit and rubbed one header tube.

One nice thing about the TTI's is they seem to sit higher up and you have a bit more ground clearance over the dougs. Both sets of headers are a challenge to get to work with a 10.5 bell and you'll need to modify the bell crank and linkage to get it to clear.

I also went for the complete TTI exhaust system but I have my leaf springs moved in so I can run 275's on the back and had to cut up the back part of the exhaust to clear the springs.
