Hello Tom:
Yeah I had my doubts about the exhaust manifolds. I might have tried it, but thats not my favorite part to redo if it don't work out. LOL
However I do have an older pair or Ansen Slot Mags (5on4 7x14)I been thinking of cleaning up and selling might give it a shot on them.
OK on the GTS owners we got the best of the Darts.
