CEL after Pypes catted long tubes. Spacers

[bluestar]

So I need some advice....Just had a set of Pypes long tube catted headers installed on my 2018 Mustang. I now have a CEL. I ran the codes with my BDX and it's the cats, code P0420 and P0430. Will a custom tune be able to delete the CEL or am I better off going with an 02 Spacer/anti fouler. If so, what size and part number? Thanks in advance!

Get a tune. The big daddy's spacers are good, but a tune is probably the best option.

A tune is definitely the plan. Was really hoping to avoid the CEL going with catted long tubes. May order the spacers as I just dropped close to 2K on the headers and install!

Go with the angled ones.

^i agree. Angled ones are better.

Some tuners won’t turn them off anyway. Spacers are cheap enough I do them to help with e85 not fouling them out as quickly.

Yeah, I've got some in as well, but my O2's are off.

VMP would not turn mine off. Have Big Daddies (straight). Worked perfect. Cleared codes. Never came back

Is there a big difference between the angled and straight?

Honestly, I didn’t know there were angled when I bought mine. All I had seen were the straight ones, but they definitely work

Sounds good to me!
