Exhaust Gasket, Greddy SP2 Options

[UTSlickVic]

Hi all!

Noticed my muffler sounding a but louder and a slight swooshing sound when hitting the gas pedal. Looked underneathe and saw that one of my exhaust gaskets is almost gone. Its the oval gasket that is at the pipe flange joint closest to the muffler. Its a greddy sp2 and wondering what's the best place to get a replacement?

Since it's a aftermarket exhaust, would a oem size not fit? Is there a size difference between the GT vs. ST size (I ask b/c I can't remember if the greddy was more sized to the GT). Greddy website has gaskets for purchase bit I'm not sure what size my sp2 is.
Looked on rockauto but all it shows me are round gaskets. Amybe there is another gasket at that joint ??? And I'm a bit thrown off by their termonolgy.
I may hit up Autozone or Orliey's just to see what they have.

Any useful info would be appreciated!

Here is a schematic of the exhaust. The joint I'm talking about is at #31320

Never mind.
Stopped by a local muffler shop and the gentlemen replaced it with a 2bolt oval metal/fiber gasket that wasn't a "perfect" fit, but close enough.
$30 ... took him 20 minutes. Ahh well.

He planned to take the old gasket and compare it to what he had in stock.... unfortunatly the greddy gasket literally crumbled into a many pieces as soon as he unbolted the flanges. He said it looked like the old gasket was all fiber vs. Fiber/metal.

Anywho, sounds good again. No more swooshing and sounds less like a typical "rice burner" exhaust. Funny all it took was a subtle change in sound for me to notice something was up.

Apexi makes a 60mm inner diameter gasket that I bought for my fujitsubo st202 exhaust. Stock exhaust for all 3sge motors are 57mm inner diameter.

Since greey made these exhaust for 5sfe cars and 3sge Celica in Japan/europe its hard to assume what your piping size is. It seems like you don't do your own car work. so only by measuring can you find out
