hey, i tried to install my nismo exhaust and hfc's last night, but the cats have a 3 bolt flange which seems hard to get to...anyone have any tips on the easiest way to get them off? from under the car....from the engine bay.... remove *such and such* first...? thanx!

 

I had a buddy do mine on a hoist, I was going to do them myself at first too, then I put the car on stands, rolled under the car, and said...**** this.

All he used was a long extention to reach the bolts, and leverage. Which I find is hard to get when a car is on stands. 1 Bolt he had to get from the engine bay too because he couldn't get it from underneath. Right hand side from the top I believe...

If you have access to a hoist, proper tools...go that route.

 

those three bolts, you will need swivel sockets. Very easy.

 

you think I can get an extension wit a swivel and an impact wrench?

 

SEARCH!!!

But since I'm already here, you'll need to get the top ones off from the engine bay, with a couple of long extensions and a swivel. Pretty self-explanatory really. If not, maybe it's a little out of your mechanical league, no offense.

 

+1

You'll need a bit of extensions to get to them. PB Blaster and breaker bar makes it a LOT easier as well.

I did it without a tutorial, its very straight-forward. If not, failsafe's ref will get you.

 

You can reach from the top as well with a long extension. Hit them with some WD40 overnight before trying to get them off.

 

+1 on the PB Blaster, it's saved my *** numerous times.

 

LOL I think itll be fine, I'm a certified tech. We always have shortcuts to get jobs done faster so I was just asking for efficiency purposes... I took a quick look at it last night around 2am and wanted to be prepared for tonight. Thanks guys and sorry for not searching. :-)

 

+1, wd-40 is a must. just get a 12'' extension and a universal too.

 

ratcheting wrenches are nice to have too when putting on the tp's

 

QFT I don't know how I ever lived without those...
