on a cobra? LX tails. they sit too high, so alot of guys weld in longer hangers. I just got longer rubber exhaust isolators from the parts store, it's a million times easier. If you're talking about my custom job, I simply cut off the turndowns on the stock GT tails and welded in the tips. They're from summit. 3" rolled edge slant cut SS tips. They're like 15.00 a piece, and they're really nice.
