To Cat or not to Cat that is the question

[Zmc Money]

Looking at down-pipes. Should I run catless, Man thing is how is the smell? lots of white smoke? Sorry for noob questions. First time buying a downpipe for a car. Atp or 2jr.

If you have never gone cat less, I would suggest not doing it. It can be very stinky on pump gas.

That said, I've run cat less in my cars for the last 20+ years.

Catless, this car isn't that bad, especially compared to my Mustangs without cats. It does stink a little. Like razorlab said though, you may not want that smell, if you have never done it. Plus, you will be dealing with emissions issues if you have emissions testing where you live.

Michigan we got nothing. I just don't want a noticeable smell when i am driving with windows down. looks like I better save for catted.

I wouldn't be the one to ask that because I'm used to it, lol. I don't really notice the smell unless I crank the car in my garage.

I would stay catted then. until you do the full stage 3.

I would be once I buy the downpipe. I would buy together.

Then it would just be up to you if your fine with the smell of gas and the loud exhaust. all the parts together should perform well thoe.

Agreed I went catted on my car at first then went catless a few months ago and the smell isn't as bad as my catless hondas though it does give a whiff of hydrocarbons every now and then if the wind is right or when parking in the garage..

Rodmoe, how come you made the switch? notice a difference in performance from catted?

 

[rodmoe]

Wanted Maxx power so I made the switch it did seem to let it breathe a smidge better

Opps, wrong cat. Here you go. CP-e.

Smells bad when stopped at stoplights, so if you do not like the smell of unburnt fuel OR DO NOT HAVE A TUNE, I would go catted. You will cause a CEL running a catless downpipe without a tune for it.

I like not smelling like gas and girls think poorly of it if your car smells, so I am going catted.

 

[Zmc Money]

I ended up buying catted, as this is my DD even though no emissions checks in Michigan.

Congrats! Either way it is a must have performance mod.
