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

how loud is the megan exhaust inside the car compare to the oem exhaust? i am looking for an exhaust that is a little louder that has the oem look.

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.

i used a cart with wheels to roll the exhaust underneath the car because its just to heavy, plus it makes it easy to install.

now place the new gasket ring to get the whole exhaust ready for installation

the front gastkets are actually rings, so to get the old rings out, i used some lubricant like wd-40 and a sharp pick to get it out.

ok, now i got all the parts together fitting correctly, i went to the nissan dealership and got an exhaust gasket kit for $80 dollars. make sure to use new gaskets whenever you are putting new parts.

finally, i was able to get everything to fit correctly, took a lot of work to do, the hardest part for me was tapping the holes, i think if you don't want to bother with making the taps yourself, you can take it to a machine shop so they can do it for you, prob cost you like $100 bucks, but you don't have to deal with it. im so glad i was able to fix this. man, that would have been $550 bucks down the drain. those dudes a meagan suck, i mean, they have good products, but their support sucks, but i don't its only them, everyone no-a-days, its the same, service sucks. its rare to find a good place with good service. its all about the money, they don't have enough staff to meet the deman i guess. what do i know?

so this is how it should look like when you align the gaskets to the catalytic converter side

now, the kit came with two gaskets, im going to use these two for now.

now insert the two studs into the new threads.

here, drill and tapped all four holes where the new resinator is going to be at. the green arrows show the original wholes, and the red circles show the new holes i made.

now tap the whole so that it will take a 10mm x 1.125 metric thread.
