I have Mac headers, y-pipe, and cat on my car, and it turns out that the cat was defective, so for the time being I have a strait pipe on rather than a cat. Without the cat the exhaust smells like raw feul, I mean so bad my eyes tear up when I stand near the car when its running. Does everyone elses car smell this strong?

 

mine does. with semi big cam and no cat.

 

That's the smell of power! My Camaro did that, but I liked it. Especially when I would drive with my windows down, and when I'd get out of the car, that's all I would smell like. It was a wonderful thing . The only downside is that girls don't like it , but oh well.

Mine isn't bad at all. Maybe the dynotune made a difference.

 

I have simular mods as you and I noticed it as well. Really bad at first but the more I drove it the less I noticed it. Don't know if it was my nose or my PCM adjusting to the mods.

 

you must have alot of overlap in your cam shaft

 

Mine's not that bad. I've got SLP shorties and !cats. I can smell it more when I took them off, but it's not terribly bad or anything.

 

Agreed. I have got the same setup, it doesn't smell awfully bad.

 

I have the CC306 cam, longtube headers into a true dual exhaust and it stinks of fuel. It has already been dynotuned and it was still stinky. It might be giving me a buzz, so I don't mind.
