Test pipe exhaust smell after tune
 

I've been running ART pipes on my Z and the exhaust makes a horrid fuel smell.

Anyone noticed exhaust smell improvement after a tune? I figure if the tune leans out AFR, maybe it won't stink as much during :driving:

Yeah... even with a tune the smell doesn't change. The only way to get rid of the smell is to go back to a pipe with some form of catalytic converter.

Mine has that smell and I have HFC's( After tune).

Update, smell no longer an issue, got used it plus after driving with ART pipes for a while it got better. However low end torque loss is noticeable, so will be tuning it this winter.
