i wuld say no to the jacks cuz its still too low from what ive seen, and yes kevinaccord if your car is turboed then the 3" piping will be fine. usually on non turbos the piping is 2.25" or 2.5"

 

You need a lift. Go to the mechanic and rent out a garage for a day. Or just let them install it.

Unless your garage somehow magically lifts the car so you can stand underneath it....but if you can do it undera jack, more power to ya (not recommended...you're playing around with death....not good)

 

so is it turboed now? or will it be turboed?? If yuo are going to turbo it in the very near future, or it is already turboed, then definately go with the 3" piping. I'm gonna get started soon on an eclipse that i would like to turbo so i was going to go with the 3" piping from the motor back. So good luck and let me know how it goes.

 

Just use some ramps. We've got some homemade ramps that my dad made who knows how many years ago and use them for everything. They are about a 1 foot tall and were perfect when I had to rmove my headers.

I would say to jack up your Accord and get some ramps under the wheels, and put the parking brake on. There is still a risk but not as much as jacks, ecspecially if you have big ramps. There wont be the most room either...but you could do it. It'll just be somewhat of a pain.
