toyota non cat cat pipes. Oddly enough side to side they are identical, the only thing that differentiates them stock north america is the o2 bung. The thing I didn't plan on was the <1" of packing all around, it's 4.101 Ø pipe with .85" packing, it leaves the inner diameter @ slightly +2"
I assumed same size outer diameter but no- it's smaller by a inch or so. I'm making some centering brackets to hold them inside the shield just like the stock cats.
I know it's not complaint or legal, This is for testing only. I do want to see what happens about the 14.7 and long term trim, and closed loop parameters.
I'm installing them after I finish the pass side manifold. Daily driver, so one at a time.
