2 1/8" TTI Headers

Yes, the problem with TTI's is that in an A-Body with Performer heads you only have 2 choices 1 3/4" or 2 1/8". Currently they don't have 1 7/8" or 2" available for that set-up.

Interesting statement , I haver a set of 2'' on mine , raised port heads /68 fastback , they clear everywhere !
