hey guys i have a 3vz-fe engine and my exhaust manifold is cracked but i have a chance to get some obx headers and y-pipe have any of you tried or even think it could fit?

from what I have heard about the obx's on ebay is that they don't fit well, but they will fit with some work.

The 1mz headers will NOT bolt up to the 3vz.

ahhhh, didn't pay attention to the engines, sorry.

just upgrade the Y-pipe, the stock exhaust manifolds flow just fine. you only need bigger ones if your FI.

^ mainly what bird said

but also, that the old obx headers had problems fitting- bigbird has the old ones installed on his car...not a bad looking design, but the front pipe on the y-pipe needed to be extended. Otherwise, no other problems were reported.

As for the new obx headers- the jpp copies- nobody knows yet. But we should know soon, as ptballer and I have a set each coming to us.
