Deleting cats.....
You'll lose lowend, gain a few more pony's up top. Not worth it IMO unless you have the cam to back it up

Thanks truckin, i have the MDS system and i think the cam will not give so much gain as on the non MDS engines unless i remove the MDS

I ran around with no cats for a while, exhaust sounded ******, smelled ****** and it had no balls down low. The stock cats are pretty high flow as it is too.

If that so i will keep the cats on but in my new custom tune the rear O2s has been deleted

I'm just curious why you're contemplating removing your catalytic converters?

In some vehicles and some older cars/trucks the cats are highly restrictive, so removing them free's up some hp/tq. With the newer Hemi's though the caats are more high flow than retrictive so there really isnt much gained from removing them and what is gained is more on the top end and the lowend then suffers.

When I took my cats off I didnt like it, yeah it'll sound alot louder. But you'll lose all your power down low and youll have the CEL on all the time. I didn't it was worth it at all IMO.

There is no inspection in my country , if i will lose the low end i ll keep the cats coz i need low end specially on sand dunes , answering your question Grubrunner, the idea of removing cats was coz i got the latest custom tune with rear O2 deleted. Was thinking about replacing the cats with small free flow mufflers.
Thanks all , I will keep the cats on.
