Alright so I installed my greddy ti-c today and there is a ring the size of my wrist they gave me with it ... i didn't know what it was so we installed it without it. Anyone know what this could be? and for some odd reason, my exhaust is blowing more out of one side than the other (when it was at cold start, more smoke was coming out of the left than the right)

 

Correct me if I'm wrong (somebody, anybody) but ain't that a gasket? I'd just replaced a exhaust system on a 91 Acura Legend and that's what it came with, that's unless you got a different gasket that came with it?
Some exhaust comes with "O" gasket rings, others come with full flange sized gaskets. Hope this helps

 

doughnut gasket goes between the cat and header.

 

its a crush ring , it goes in between the cat and the greddy exhaust , it fits the inside diameter of the gasket.....

when i installed my TiC i didnt put it in , started the car up and checked for leaks , had a nice leak right at the cat and exhaust flange , unbolted it put that ring in bolted it bac, up , no leaky

If you got a TP then chances are you don't need it cuz it uses a flat gasket.

 

correct


.....the test pipe should have come with a gasket that has the crush ring built in

 

Well I used the one they gave me which was a completely metal looking gasket (looks different from the one I got on my testpipe, the testpipe one had a silver covering on it) should I swap it out with the old gasket that I had on?

 

yea use the one that came with the test pipe

 

is it okay if the threading part of the gasket (the hole) is kind of broken? I'll try to put up pics to explain this more. It's not that it's like snapped in half, but underneath the silver covering, the threading kind of crumbled on one side
