Do you have any issues I just bought a 3" eBay exhaust and the downpipe gap to the o2 housing won't let my bolts reach it and screw on.

Also the gasket doesn't fit snug it's got some play is this normal?

 

On my power DP I went with the OEM donut gasket! and it doesnt fit snug. Some dp dont require a gasket i think.

 

I run a Works downpipe with the OEM donut gasket and it does not fit completely snug at all.

 

What would I use? Is it one of those flat gaskets? Or will it still bolt up without a donut gasket?

Not sure what to do at this point

 

permatex will help small leaks as it did for my leak with an oem donut gasket on a greddy o2 housing with greddy downpipe.

 

You're not supposed to use the OEM donut gasket with WORKS downpipe. The WORKS downpipe comes with a ring adaptor and a donut gasket which is bigger than OEM. Other brands of downpipe that require a donut gasket will work with OEM donut gasket.

 

Yes you are right. I had reused me OEM gasket with a different downpipe that I had used before the WORKS downpipe.
