Cat Delete mod and FUMES!

[ArabianOak]

Hey gang,

I got the cat deletes a few weeks ago and have noticed the fume smell is very strong in my cabin. The side exhaust is definetly pushing alot more exhaust since removing the cats but the smell is pretty bad inside the cabin even while moving, especially if the windows are up.

I would assume since the side exhaust is pushing so much more exhaust with the deletes, this would be where my smell is coming from, but wanted to ask if anyone else has experienced this with the cat deletes??

I checked for leaks but have found nothing. Should it really be this fumey just with the cat deletes?

thanks!

I was going to say that you might have a leak possibly from the cat delete to the headers or cat delete to the h-pipe. I don't think the smell you are getting is from the side exits since they are close to rear tires. How did you check for leaks?

It's the side pipes. I guess you need to decide how many brain cells are worth 10 hp.

i hated the fumes when i first put my o/r x pipe on. i considered putting the the factory mid pipe back on. after awhile i just got used to it and it didn't bother me anymore. i'd just give it time and you'll get used to it.

E85 will cure this.

Embrace it, love it, enjoy it. It's what fast cars smell like and eventually you won't want to own a car unless it smells like that.

Turn on recirculated air. Problem Solved

Where does the smell come from if there are no leaks? Is it really the side pipes? Did the cats really prevent all of those fumes?

Shaun, why does e85 cure it?

E85 doesn't have that smell that sticks in your cloths, hair, etc.
Just a sweet smell that doesn't absorb.

I spray paint for a living so my brain cell count is already low !!!!!

This is the exact reason why I didn't install the delete pipes I have had in my basement since winter. Also why I haven't had the side pipes fabbed up to my off road X pipe yet.

I think the smell from the exhaust will drown out the cabin too much. If the car was an old muscle car, I'd say "who cares" but when driving around a car your making payments on, smelling like exhaust to me isn't cool. The smell from the off road X pipe really isn't bad because it's mostly behind the car. I'd rather smell that than hot, stinky cats any day.

yes the cats prevent those fumes, its simply a fact of life if you choose to go catless. you really need to google what catalytic converters do to understand.

yes.

try long tubes next for even more awful smell.

Long tubes, cams, no cats. Yummmm. Add in some race gas and you're cooking

New cars burn so clean that in certain conditions the exhaust is actually cleaner than the air going into the intake. When ETOH burns the byproducts are harmless CO2 and H2O. What stinks when gasoline burns on a catless engine are the unburned hydrocarbons. Since E85 is 85% ETOH it burns much cleaner than straight gas. It sucks that I live in the center of the "clean air state" and there isn't an E85 station within 200 miles.
