n e one got pics of their jdm omni power test pipe installed on their car? do u need the jdm donut gasket also? reason is i just bought the jdm omni power test pipe n it doesn't fit my jdm header with donut gasket. so am assuming they sent me the usdm one. but would like to see a pic if ne one can help me out. tia.

 

What is it about the test pipe that isn't fitting? Is it 2.5" diameter?

 

it's not fitting snug on the donut gasket.... i'll try to host pics up so you can see. give me a minute or two.... the inner diameter is not quite 2.5 but almost.

 

the jdm test pipe has a HUGE collecor, the usdm has a normal collector.

compare your test pipe with your cat, if it looks the same on the header end, then you got a usdm one

 

i don't have a usdm cat on hand at the moment to measure it. but i'll have the pix of the header collector up and the test pipe to show the difference.... maybe i got the wrong donut gasket on, it came with the used header that i bought off an
h-t member.... i mean it barely fits over the donut gasket on the header.

 

Here are the pictures.....

 

That's about right. The flanges shouldn't touch, it's a ball and socket joint for flex. You need to use the stock springs with that joint.

 

i thought that it should sit more snugged in??

 

It will snug up a bit more once you get the stuff tightened up.
