This isn't an issue though since the stock cat will come right off at that point.

Some guys aren't so lucky though and have to torch/cut the bolts off. Just soak those puppies in PB Blaster the night before and hope for the best.

You'll have plenty of room with jack stands. We actually did the second install with just the front on ramps.

Do you think it'll be hard to break the top bolt loose even on a brand new vehicle? Thanks for the advise. I was more worried about having enough room to maneuver pieces of a CBE because they are longer. OK, I may have to go buy some tools...cool!

Both cars were low mileage and it still took some serious torque to break them loose. Mine had around 1500 miles on it. With the proper tools it's not hard though.

Yes... as my guy says, "They come pre-stripped from the factory!"... lol Even on my 2010 G37xS sedan that I picked up 2 weeks ago. heh

They had to use the torch on my driver's side bolt.

Other than that, install went fine. Took more than an hour though because of that one damn bolt.

I did get an SES light today though (had them installed yesterday)... P2A03... I cleared it with my OBDII scanner, and I'll see if it pops up again. Hopefully it was just a fluke, but we will see.

I guess that code has to do with one of the primary a/f sensors. AFAIK, the battery was never disconnected. If it pops up again, I'll try that.
