anyone have a ballpark figure of how long it should take to do a y-pipe, cat, and cat back install if the car's up on a lift, using all air tools, and an infiniti mechanic?

 

it took me and a friend about an hour to do the y (rusted nuts, lol, and no air tools). since your doing the entire system, proll no more than an hour and a half.

Sray down the bolts on the y-pipe flanges, and the bolts going into the cat from the y with PB blaster first. Then unbolt the rear section of the exhaust (part with the muffler), then unblot the cat from the y. drop that down as a unit. Unbolt the y-pipe. start by bolting up the new y, then cat. then bolt the new b-pipe in, then the rear section. Honestly shouldn't take more than an hour and a half, unless you break a stud or something like that.

 

alrighty, thanks bro. i'll get pics of everything on the .org as soon as i can with it

 

This is a really easy job to do. The y is probably the hardest part of the whole operation. Getting to some of those bolts in the back of the y-pipe off makes me think that nissan has some magic fairies to do their work sometimes.

Anyways, the process should take you with a mechanic and the right tools: 1hr - 1 1/2hr tops.
