Hi all. I'm newly registered on this forum, and I'm hoping that some of you will share your experiences and insight.

Does anyone have recent experience passing the California smog ref inspection with their Toyota 3.4 swap? I am about to undertake this swap and am trying to figure out what exactly to do with the exhaust system. Here's some background: my donor vehicle is a 2004 Tacoma 5 spd. manual 4x4; the recipient is a 1995 4Runner 5 spd. manual 4x4. Donor and recipient are (mostly) complete and side by side in the garage. Donor tipped over off road and was totaled, recipient's 3.0 has a blown head gasket.

Please let me know what worked for you and what didn't, and if you know of any particularly lenient refs.

Thanks in advance!

Exhaust has to bee on the same side as the Tacoma, ECU has to be the same as the Tacoma, NO CEL, and Fuel likes have to say fuel lines.

That is all I can think of when my brother did the swap in the RV.

Thank you SafetyDang. I have heard similar things. I spoke to a smog ref in Los Angeles who said he would be OK with rerouting the exhaust as long as the 3.4 stock exhaust dimensions are maintained. Has anyone passed recently with driver side exhaust?
