These are Kinetix HFCs. Is this hole factory or is it from the addition of another sensor? Anyone know? It's only in one cat.

 

Some factory cats have a drain for condensation but that looks a little too big. The stock steel tube they use for that joint looks like it had a hole in it when they made it. Welder probably noticed it after he started welding and sent it out anyway.

 

Larry, ooops. I forgot about that. It's an EGT probe hole. If you don't have an aftermarket EGT, you should have a muffler shop plug it.

Egt?

 

exhuast gas temperature. i say leave the hole and put a gauge in!!

 

And what good would that do me? What do they cost?

 

Would do you no good.....If you go FI...yes , then it would [ some what ] it should be as close to the exhaust port as possible to be able to tune with it

 

i have no plans in going FI anytime soon.

 

yah but it looks cool aslo i think.
