So I was thinking about buying a ZZP catless DP because I dont want to install the wideband o2 on the stock DP. Is catless really worth it for the extra HP or do they just make you and your cab smell like everyone says.

The LNF has a wideband from the factory. No reason to add one unless you just want to have the gauge. A high flow cat will make basically the same power as catless. I think most people go catless because it is much cheaper.

Yes I meant for the Air fuel gauge, do you know if the smell is noticeable inside the car while stopped or while driving?

I have a cat delete on my Evo and with stock exhaust I still get some smell. Its nothing crazy or unbearable tho. Doesnt bother me but there is a smell.

I use to have TurboXS catless and it smelt bad if you were behind me.... especially drive thru's.

Drive thru was really the only time I smelled mine and I ran e47 so it didn't smell bad. If you have a full exhaust it's only mildly louder. Either way catted or not it does help performance. It's only like 4-5 hp different catted to catless so it's a personal choice.
