Not much to be gained from swapping out the factory STi uppipe for an aftermarket unit unless you are planning on much more mods than what you already have.

Oh, removing and replacing the uppipe requires you to unbolt the passenger side engine mount and lift the engine so that the flange can get past the block and frame of the car... massive pain in the ***. I will take off and put back on my headers 3 times before I do the uppipe again!

What up-pipe do you have? I assumed all were the same. I have a PDE and it said in the directions to loosen the engine mount and jack it up about an inch. I tried to pull it out with out lifting the engine... I didn't try for more than 15 min or so but gave up trying to solve the angle puzzel and went for the engine... It made it easier to remove.

....nobody in their right mind would mess with the UP unless it is abosolutly necessary.....and there is NO NEED to jack the engine to do an UP....and NO NEED for an UP on a stock turbo'd 2.5 with no UP cat unless the stock pipe is leaking or borked....

I agree though, if mine didn't have a pre-cat I would not have messed with it. When I did my install I jacked up the motor a little because I didn't want to remove the turbo. I'm not sure it could have been done w/o doing that, at least not easily.

I actually got taken to the hole by a shop in So Cal before I knew much about my STI. They said that the up-pipe would help and I believed them... good news is that I paid 90 bucks for a PDE up pipe. Not too bad (they could have taken me for a high dollar item!). Hindsight 20-20, I would have left the stock up pipe.
