Well its time for my state inspection and emissons and i have a RnR 3" TBE (with test pipe). I dont want to take off the whole exhaust and put it back on a day or two later so I would like to just take off the RnR test pipe and cat back and throw the factory unit back on.

Do you guys think the factory cat will bolt up to the down pipe?

Also I have cams and custom tune from shiv, If I throw the factory exhaust back on will that cause any problems?

 

HOLY CRAP!! I just took off the exhaust and drove around for a mile or two with just open down pipe and the car fu*King screams!!!! it seems a bit quicker also.

(I feel a little light headed also... probally from exhaust gas getting into the cabin

 

Lol

 

If you have your cat there is nothing going in your cabin

 

The cat is not on there yet... I took off my exhaust and since it was off I wanted to see what kind of power diff. there was with just the open down pipe... after a mile or two I went back home, thats when I felt light headed.


now that I have the exhaust off, I put the cat up to the down pipe and I dont think its gonna work, So I guess I will have to put the factory downpipe on also.

I just hope the factory downpipe fits the 3" O2 housing I have on there

what a hassle



PS. Is there any one is charlotte that can hook me up with state inspection and emissions?

 

okay... so i tried it and it does not work... the 02 housing is to big for the factory downpipe. What really sucks is that when I installed the 02 housing i cross threaded a bolt so there is no way in hell I will be able to get it off with out breaking that bolt.

My other option is to get a high flow cat with a flange on one end that meets up to the 3" down pipe and the other end that has a flange that will bolt up to the factory mid pipe


oh why oh why did I modify this stupid car

 

what a pain in the a$$... you really need to find a "hookup" for the emissions...

 

I had a catless WRX and found a good shop through a friend. As long as I didnt have a CEL it passed emissions. Just call a muscle car garage around you til you find a cool one.
