How To Install A Cat Back System Exhaust On 300zx Z32 Car

ok, i finally found a way to do this. since the holes didn't align, i will have to drill and tap my own. im not getting anywhere with the guys i bought this from. so on this pic, the first step is to drill a whole, im using a 11/16 drill bit. first make sure you measure to align both exhast flanges.

I tried ordering the 11/16 drill bit but it seems way too large than the one on the pictures. Any other sizes that would work?

For 10mm x 1.25 tap, use a 8.9 (11/32) size drill bit.

after you have installed the resinator and catalytic coverter system, you its time to install the two exhaust mufflers. make sure to align the pipes correctly and that everything is tight.

this is one of the best upgraded i did to my z, im very happy it worked out. if you are going to buy a cat back system, make sure when you buy you make sure that you tell the exact model to the vendor. sometimes there are mistakes, for example, in my case, i think, they gave me a turbo cat back, but my cat is non-turbo (na) so make sure and check with them.

as you raise the exhaust sytem, be sure to keep an eye on the 02 sensors not to damage them.

now with the factory jack that came with the car and a piece of wood, you can raise the two front pipes to help you raise up the exhaust system.

try to align the three hole in the headers, putting these bolts will make it easier as you install each bold holding the exhaust system as you make your way toward the end fasterners.
