I'm sure most of us been on dezod.com and noticed the oem donut gasket issues with the invidia s-pipe. For awhile I've googled a solution for this problem and found nothing that would help. Last week I ordered a dezod replacement gasket (just to see if it would work) along with the s-pipe. I finally installed everything over the long weekend and this is what I got.



and this is a side by side comparison dezod on the left and oem on the right.



as you can see there is a size difference. The dezod gasket fits nice and flush in the s-pipe. I did compare it with oem one and it was small.

After installing the dezod green header, s-pipe, urethane hangers and dezod exhaust we tested for exhaust leaks and found none.

I have the same exact setup. No issues here as well.

 

Awesome news! Thanks for sharing.

 

RLO has a newer version header which is very different than yours Japanjay. So apples to oranges.

 

Damn my stock header and s pipe didn't look like that when I removed it. Lol but regardless fits right no leaks with the new system.
