Merry Christmas, fellow Maximaholix....quick question on exhaust. Over the fal, I installed a ss budget y-pipe, but just used some bolts that would fit that I found lying around the shop. I hear a bit of a leak coming from the junction of the cat and the back of the y-pipe...I need to use an oem gasket, rather than the junky one that was provided with the y-pipe. I want to use the correct bolts, if I remember right the cat is threaded. Thanks guys.

 

Merry Christmas.

exhast bolts are 14mm. i believe 1.25mm threaded.

 

I thought the exhaust ones where 1.5mm threads?

 

might be not too sure

 

They are M12x1.25, head size is 14mm. I have a box of M12x1.25 nuts that I use at the shop for Nissan exhaust studs.

 

Thanks, guys... much appreciated
