I already have 4 of these; what type of air tools are you suggesting? Btw, I'll have to figure how to remove the rubber mounts.

The air tools are just because the nuts and bolts on the exhaust/cat are quite hard to loosen by hand. I went to a DIY garage and rented a lift.

You can get special tools to handle the rubber mounts, but some people just use a screwdriver or something. Also it helps having someone help you holding stuff in place while you work. I did it alone, and I do not recommend it!

Here's a youtube clip that shows you the basics of exhaust replacement.

Considering the side exit one. If you don't mind, I'd like a DIY for removing the stock one!

Removing the stock exhaust? 3 nuts holding the midpipe to the cat, 3 rubber mounts holding the midpipe to the car. Two bolts+nuts holding the rear muffler to the midpipe and another 2 rubber mouts holding it to the car.

Having air-tools and a lift available reduces the risk of serious injury, death or worse
