Well, Borla finally got my warranty replacement header to me. My previous Gen.3 had a pencil sized HOLE in it, and a crake the was so bad it would rattle/vibrate against the rest of the header making my car sound like a riced out honda..
The bends,welds and finish of the new Gen. 4 are MUCH better. The fit is damn near factory (as compared to the 6 hour install of the Gen.3)....
The Gen.4 lacks the support "strap" that connects the tubes together, this strap would cause the cracks due to thermal expansion so Borla finally just removed it and they are just as strong with out it.
So, if you have a cracked Borla, call them and have them send you a Gen.4...its worth it.
