Posting here because I only have 2 total post and can't post in DIY area yet
Last week I ordered the TurboXS Cat back exhaust from summit racing. http://ift.tt/1DZgGyk
I read up on here that you need to install longer exhaust hangers to prevent the tips from burning the plastic. They are Correct! I was to impatient to order the ones recommended so I went to my local Autozone, Advanced Auto and O'reilly's to see what I can get locally.
They all sold the 4" walker exhaust system hanger for about $5. I bought 4 of them.

Remove Stock Exhaust: Time 1 hour
I used ramps to get the rear end up in the air. I'm sure you could use jack stands too, use what you have. There are 5 rubber hangers and 2 nuts and a ground wire holding the stock cat back system on. You do not need to separate the muffler from the connecting pipe between the cat and the muffler.
2 on the passenger side
2 on the driver side
1 above the connecting pipe
Lube all 5 of them generously with WD 40 or something similar and let sit for 5 to 10 mins. While you are waiting you can locate the 2 bolts you need to remove.
DO NOT WASTE YOUR TIME REMOVING THESE!
This is what your looking for. 2 bolts with springs behind them.
I removed the bolts and springs first and then worked on removing the exhaust from the rubber hangers. It is a little annoying but they will all come off and your exhaust will fall to the floor. Don't forger the ground wire! remove that before you remove the hangers.
Prep for install: (first time learning as i go) 1 hour.
The First problem you will come across is the flange on the new system will not clear the humps on the 2 bolt ends coming off the cat. the second is the supplied springs OR the stock springs will need to be cut to fit.
*There may be a better/correct way but this is what i did*
Locate the 2 bolts coming off the cat flange.
Grind down the bottom of the hump next to the threads. Do not grind the threads! you only need to take off about a 1/8 of a inch to make your new flange fit. I took off a little at a time and tested it until it fit over the humps.
Once the new flange fits over the humps you will need to cut the springs. i used the stock springs and cut one layer off at a time to see what works best test fitting each time. I ended up cutting off 3 rings witch in the end was basically cutting it in half. If you have a way to cut one in half without distroying the surrounding rings, go for it. I was using a 4in cutting wheel so i cut 3 rings off both stock springs.
Once you can get the springs on with the bolts behind them and it threads, your ready for install.
Install New Catback: Time 1 hour
Be sure to use the new exhaust gasket when installing your new system.
Install your 4 new 4in walker hangers on muffler section of the new system. Do not connect the connecting pipe yet. Once you have the mufflers hanging on the car install the connecting pipe to your cat. I did not use or replace the hanger for the connecting pipe.
Once you have the new gasket, springs and bolts tight use the provided hardware to connect the mufflers to the connecting pipe. Make sure everything is tight!
NOTES:
After install i checked to see if there was any clearance issues. The pasanger side tip was very close to the plastic and the driver side was about a 1/8 in away. I did a test run around the block with some warm up rev time in the drive way. I noticed the plactic on the passanger side was just about to melt so i turned off the car and let everything cool down. I changed the hangers to 2 each on the 2 back hangers near the tips and nothing on other 2. the weight of the exhaust brought the system down about another 1/8 of a inch and gave enough room to not melt the plastic.
I've been driving with this setup for almost 2 weeks now. I love the sound, the doubled up hangers keep the exhaust in place and it was all done solo in 3 hours.
I hope this helps anyone looking to do this install on their S2.
