Hey guys, im going to be installing a megan downpipe in a couple of days and wanted to know if this gasket that comes with it is used to replace the stock doughnut gasket. It also only comes with 4 bolts. Does that mean I reuse the stock spring bolts? or do I use 2 on the 02/downpipe and the other 2 on the connection to the test pipe? If thats how it is what do I use for the hangers on the downpipe?

Here is a picture of the gasket and hardware included:

 

I think u re-use the old bolts at least that's what I did with mine...

 

Me too, I reused my spring bolts.

 

You reuse the spring bolts that connect your stock downpipe to your stock o2 housing and use the hardware they provided on the test pipe section. You may use the doughnut gasket that is in that bag as well to replace the stock one.

i would recommend using the new gasket. Nothing is worse than putting part of an exhaust on, to only have a gasket blow out a few days later and have to get back under the car to replace it.

 

Use new doughnut gasket, 2 bolts for downpipe/cat, reuse 2 spring bolts for 02/downpipe. Might as well get a new gasket for the downpipe/cat while youre at it!

 

When I got mine, the gasket was to big so I could not not use the spring bolts. Had to get some regular bolts and washers. It started leaking after a few miles so I got a oem doughnut gasket and have not had problems since.

 

I had to use the OEM gaskets and spring bolts with mine. The one that came with it was bigger and wouldn't fit.
