Why when i do wot do i smell a sulfur like smell, is there a leak by my precats?

 

im pretty sure thats normal, unless what you smell IS a sulfur smell (like rotten eggs) then you might have a problem.

 

my gf's moms tl smells really bad after WOT my tl-s not even a fume lol

 

I think it's normal after removing the 3rd cat. You may want to try a different brand of gas and see if that helps.

 

I have an 07 TL-S that is stock, but I experience this smell after WOT as well. Is this normal for cars that are stock? Thanks.

 

Yes, its normal for any car. At WOT, the cats are overloaded and the stinky exhaust goes out unconverted. You should occasionally encounter this while just cruising because some guy up head went WOT.

So if some guy is tailgating you then just go WOT and he'll get some of stink.

 

i noe for a fact my 07 tls does not smell like my gf's moms tl
