Hi guys,and gals,sorry iam not jimmy savile,i wonder if you could help,ive just had my tt converted to a manual,and i thought the exhaust was blowing a little and it seemed a little week,thinking if the exhaust was blowing mybee that would explain it,so got under the car this morning and noticed that on my exhaust there are two metal pipes that come off each side of the exhaust,oh by the way its a kakimoto exhaust,these pipes join flexible hoses then go into metal pipes and disapear into the engine bay maybe under the wings,the thing is both these pipes had not been connected up again ,is there a reason for this, idont want to connect them up if they have been left off for a reason,the car when you pull up would cut out as if it had a vac leak could this also cause this any help guys would be great.thanks.

You don't need to worry about these, can't remember what they're called but I believe it was a little fiddle Nissan added to try and reduce the emmission level. Mine were cut back when I replaced my exhaust with no ill effect several months back.

 

I'm sure someone on here will give you their name and explain exactly what they were for if you are interested.

If you type in AVI in the search, and then look for the post (6th I think) by High Explosive, it should tell you more about them.

 

They are really called AIV Valves.
