I am in the process of placing an order for
OEM 2 Bolt Exhaust Gasket #20692-1E810

Is is sold as a set of 2 for $9.72 ?

That particular gasket is sold individually. You would need a quantity of two.

perfect! thanks

will these fit onto resonated megan racing test pipes? and does anyone know if my current gasket got a leak in it could the crap from the gasket gotten sucked back into the engine?

Bought a set of these last week and the quality of the header to testpipe gaskets is fantastic. They fit perfectly and look very well made! Unfortunately Z1 sent me the incorrect size gaskets for the testpipe to catback joint and I didn't find out until the car was up on a lift taken apart at the speed shop getting billed by the hour. The GTM testpipes came with very poor quality gaskets that unfortunately had to be used due to the error.

I emailed Z1 and they apologized for the error and are sending me new ones however the car is buttoned up and not planning on taking it apart again until the gaskets fail. I suppose when the time comes I will have a nice set rolling around my garage waiting to be swapped in.

Overall fantastic product and great customer service. I'd vouch for the quality of these gaskets for sure : )

Hey Chuck, i just recently bought some test pipes (For a 350Z) to mate with my momentum headers. Does this new style gasket come with them? They are the test pipes for the DE engine. Thanks!

Hey,
Unfortunately those will need a set of gaskets. The 350Z used a gasket from the factory similar to the one we had custom made for the 370Z.
You would need to pick up a pair of these for the momentum headers because we don't include them since the 350Z came with them stock.
OEM 350Z / G35 Exhaust Gasket (Manifold to Cat)

Sorry it's a little complicated for momentum header use.

No worries! I went to Nissan and got the OEM ones. I was really suprised how fast you guys got the TP's to me, I ordered Friday, and they came in Tuesday morning. That is kind of a big deal when getting parts shipped to Maine, and the backup from the blizzard we had. Just wish i got one of those cool z1 decals :-(

Thank you Z1 for making these! Completely blew out the composite gaskets that came with my test pipes and these sealed the exhaust leak easily and have been going strong. Awesome stuff!

What is the diameter? 2.5 or 3"

Just installed these yesterday and they leak EVERYWHERE. I'm not sure if the seal activates by heat, but when we first started the car up all three sides of he gasket leaked and you could even see a gap. Put a lot of RTV on them but I fear they are still leaking.

Z1 please advise

Put a set of these on day before yesterday and leak like hell too. Never had a problem with leaking gaskets before these and I've always just used whatever came with the pipes. Even put an impact gun to them and still leak. Going to put regular gaskets back in and toss these along with the $50 they cost into the trash.

Update: placing an order for Fast Intention's gaskets. They are cheaper and look more for fit for the job than the Z1 units upon closer examination.

I have never had a problem with Z1 products before, but am rather disappointed in the performance of these supposedly heavy duty gaskets. The set of two 2-bolt 2.5" gaskets I purchased for $7 were thicker than the $35 "multi-layer metal" ones.

On a positive note, I sent Z1 a message about this last night and woke up to a response from Jon this morning. The product may have been faulty, but at least their customer service isn't.

Damn I have a set of these waiting to go on. =( Should I just save myself the headache?

As someone who was heartbroken after a whole day of exhaust fabrication, yes. Order the Fast Intentions gaskets and save yourself the frustration, $25+ shipping for peace of mind is well worth it.

Depending on what happens with Z1 I'll drop a one star review to deter other people from suffering the same fate and send them back to the drawing board for a better design.
