Today I installed the Cattman Y-pipe and the RT Catalytic converter. Now when I drive, I get this weird smell like something is burning. When the car is idle you can smell it. Can anyone help me out? It is a 95 Maxima.
The O2 sensors did not go on, so I did not bother resetting the ECU.
thanks

 

Hmm.. im not sure about the Cattman but when i installed my Stillen Y, there was a funny odor for about a day and it went away. I know its from the coating on it (Ceramic coated).

 

I think you're suppose to reset your ECU after installing a y-pipe because it has to adjust itself due to more airflow thru the exhaust.

 

u will have a weird smell coming out from it...everyone has that put on an aftermarket y-pipe...it's the grease from the y-pipe that is burning...it will go away after u drive it some more

 

I hope this smell goes away soon. SYNKI, I dont think the cattamn pipe has a ceramic coating on it. Its stainless steel. I am just keeping my fingers crossed.

 

FWIW, when i installed my headers and my exhaust, it smelled for a day and a half also.

 

Life is absolutely correct. it will go away within a few days. my smell went away after about 80 miles.

 

i dont know if it applies, but i know someone who has one of those straight pipes instead of a cat, that thing still smells awful, hope its just the y-pipe and temporary, bc it could be the cat no fully burning all it needs to

 

good point, your cat might be overworked. since the new y-pipe removes 2 precats, the air is not filtered out as well.

 

good news people, the smell is gone.
thanks to all those that replied.
now I need to get that Apexi WS catback system

Headers? did you get them shipped in from NZ?? i know there are no headers for the 4th gens right now. by the way that smell shouldn't be there, you need to replace all the O2 sensors!! hurry up your new cat is gonna get ruined.

 

The "cat" catalyzes a reaction which turns carbon monoxide into carbon dioxide, that's all. Carbon monoxide is odorless. Most metal parts have oil on them from machining, it burns off.

i know, i was just messing with him. i love all these newbies that get paranoid and post about stuff that has been discussed 100+ times before.

 

dmbmaxima88 , I recognized you're subtle sarcasm. The guy a couple posts before yours seemed a little more concerned. "filtered"??
