I want to change out my midpipe and install a coupe midpipe. Can someone point me in the right direction or give me verbal instructions. On a scale of 1-5 how hard is it? thanks

 

I just had mine installed at a local Marco Muffler last week. You'll want space under the car... I jacked my car up at my house to get ready to install, but a floorjack doesn't allow enough space.

1st problem with trying this with only a floor jack: The bolts are on there very tight (14mm) so you'll either want pnuematic tools or more room to get agressive.

2nd: There is a 1/4 rod to protect the exhaust from hitting the driveshaft. You can bend it out of the way....BUT....unless you have a torch to heat the metal, you'll be pounding on it for a while. Again, another reason to have more room under the car.

3rd: Not as difficult, there is a heat shield that needs a lil bending to avoid rattling.

I paid $60.00 to have mine installed, watched the guy the whole time and it took hime 45 min. So for my peace of mind it was $60.00 well worth it.

pay someone to do it... I ran a full after market on my coupe and unless u have a lift its hard as hell to do. Theres jsut not enough room to move around. Fortunate for me I was patient and after 3 hours baking in the heat I was able to do it. The bolts are as tight as everyone claims. Its finding the right leverage spot to turn them. If your up for a project DYI if not 60$ is cheap to swap.

 

Well I just finished installing a coupe midpipe on my 03 sedan. I must say it was not nearly as difficult as I thought it would be.

I was able to get 3 of the 4 bolts off rather easily after spraying PB Fluid on them for about an hour straight.

The last bolt was a true pain the rear... Trying to get it off I rounded the corners and it became clear I needed to cut it off. After quite some time of hacking away at it with a dremel (and tons of cut off wheels later) my neighbor brought over his handy grinder and was able to cut it off in no time.

After getting that bolt off we unbolted the brackets for the exhaust hangers then took them off outside of the car (much easier imo).

We had the new one on in less than 20 minutes of getting the old one free.

All in all it wasn't that bad and was quite enjoyable. My advice for another DIY'er is to pick up a grinder and spray tons of PB fluid on the bolts and let them sit for some time before trying to take them off. I also found it handy to take off the rear driver's tire to get one of the bolts off that connected to the muffler, it allowed easier access and I was able to get more leverage on the bolt.

Also I didn't have to do any heat shield bending or bar whacking... it fit nicely in place with no problems and no rattling....

 

I have the opportunity to buy the midpipe from a 350z. will this be a direct replacement for my 04 sedan midpipe, or does it have to come from a g35 coupe for easy install?

 

350Z midpipes require some lengthening to fit the sedans.

The coupe's midpipe only requires some heat shield bending to fit.

 

Not to try and thread jack but, does anyone have the Nissan part #'s for the gaskets on either end of the pipe?
