kursplat- thanks for that arrival. I’ve got the TTI “x” system on manifolds on the 66 Barracuda and I’m not happy with the 74’ 318 in there now. I purchased a 69’ 318 with low mileage I’m going to go thru over the winter and I will now possibly invest in shorty headers from TTI and see if they will sell me just the head pipes to match my existing system. Appreciate the info.
Joe
