CEL with exhaust work?

SuckMy_Nick · 03-25-2013, 06:43 PM

I have an AA 2 tune, not sure if it matters.. But I want to delete my secondary cats and res.. Will I get a CEL?

I've searched and found people who don't have tuned getting CELS, with the tune help?

No you will not get a CEL if you delete the secondary cats. The second set of o2 sensors are before the secondaries.

Now if you remove the primaries then that's a different story...

That's what I thought but I was reading something that said otherwise
