70 B-body tti Hemi 2&1/8" primaries, & 3" pipes. Had to drop the trains cross mount maybe 1/8-1/4" cause the pass side header was maybe an 1/8" from the T-bar.
The rest was the typical "bolt on" with some cut off of excess material, expanded the pass reducer a tad for better slip fit etc. Cut of the muff outlets ~1". Figuring out where to cut the tail pipe so the tti stainless tips can have a factory bumper over hang.
But when it came to the Huge tti muff hangers I just no likey, a bit Big and gaudy to me. So since I rotated the band clamps bolts out of sight to the 12 O'clock position, that gave me the excess bolt threads up there for mounting hangers completely out of sight. May not work for the OEM look, but works for me. Got about 1500 miles on'm, & no snagging myself on the typical hanger threads while creeping around for clean up etc.
Speaking of clean up, I see somp'n that needs a cleaning.
