Catted section 1 options - OBD 2 compliant

[Ragincajun5220]

Researching catted section 1 options to use with euro headers that will pass US emissions obd2 testing

seems like euro section 1 (hard to find and expensive), super sprint section 1 (crazy expensive) are the choices

Anyone aware if this from schmeidmann would work? Seems unlikely as it’s 100 cell but not sure.

anyone aware of any other options?

There was a thread on this very recently. A few of us have welded HJS cats onto the stock section 1 for a cost effective option.

Nice! Did you weld in o2 bungs as well? Do the factory sensors fit?
