So do you just tell people to re-use stock O-ring or do you feel you dont need one at all?

Also, I'm sure you've heard that 2k-3k rasp/flutter from the test pipes...How well do these pipes dampen that noise compared to say, the HFCs ??

So I fitted my resonated tp's today. And I can't see how anyone could reuse the ring gasket for the header flange. It simply does not fit over the male part of the gtm flange due to the diameter being larger. I have both brand new rings from nissan and the used ones from stock. And both do not fit. I used ultra copper liquid gasket by permantex. Fingers crossed it doesn't leak.

I know this thread is old but I feel my experience should be notes for interested tp buyers.
