yeah, the outlets are different, but the head flange is the same.I'm sure that doesn't mean they are bolt on to the rest of the exhaust though right?
A little off topic (sorry OP)
Did you ever get the LS1 wiring to 1uz worked out?
Thanks Gutz. That's the answer I was looking for. Like I said, if the exhaust headers from a 1 UZ vvti and 2uz are interchangeable, it will be worth the effort and money to import decently made and developed units from the states. Those JBA units looks like they are properly build..I have a set on my 3UR-FE. Pretty good quality, had them for 3 years, still look new.
