hi. i have a logic performance downpipe. i contacted them but havent gotten a response yet. i need a donut gasket that connects the o2 housing and downpipe.
here is what the downpipe looks like for reference- thanks in advance !

 

Why won't the stock one work? I didn't change mine when I installed my downpipe...

 

^ if the stock one works then i will be heading to the dealership to get one. can anyone else confirm this ? from their website. "This is a great downpipe retains stock mounting locations and uses supplied donut gasket." I THINK i used the supplied gasket when i installed it. It did look bigger then the stock donut gasket though.

 

I used the stock one and it works fine. I have the one they gave me with my dp if you want it?

 

cool. did the one LPI provide appear bigger? i might end up using the stock one. the smaller stock one shouldnt cause any restriction ? i'll let you know if i need it. thanks alot !

 

Let me know and I will just give it to you. The one that I got did appear bigger so I used the stock one and it made it alot easier to bolt right up. As far as restriction goes, I dought the stock one makes any diffrence

 

I have one in stock and can do free ground shipping if you want to save a few bucks and have time to wait.
