CP-E turbo back exhaust

[xBLUECALXx]

I was looking at purchasing the CP-E exhaust system and I had a few questions regarding it. First I want the downpipe to have a cat and on cp-e's website they give me a few options on the o2 bung and cap. Do I need any of these options? I was going to purchase it from SU and they don't even give me those options. My second question is about how the install is. Does the full exhaust mount to the stock mounting brackets? How's the difficulty? Are there instructions?

There are instructions. The install is fairly easy, the only problem you'll run into is actually getting the downpipe out and the new one in, there's not much room. It definitely fits though. it all fits on the stock mounts perfectly. The O2 bung can be used if you want to install an a/f gauge which is always a good idea to help monitor and if you plan on tuning in the future.

I've got the AP so I'm telling myself that this will be it on tuning. Does it make the check engine light come on at all?

well even if it throws the check engine light..u can diagnose it with the AP and clear it youself

I have never seen the cp-e instructions for a downpipe or exhaust, but if it is anything like their other sets of instructions, they are well written, and documented with lots of photos making it easy to understand

okay so I was reading up on SU's website and they recommended that unless you're going to upgrade your turbo you shouldn't get a downpipe but rather their test pipe. I have an AP, TIP, and SF, and the only other thing I was planning on doing to my car was the turbo back exhaust. Should I go for the full exhaust or listen to SU and get the test pipe and catback?

I would say get the catted downpipe with catback. You're going to see more gains from the downpipe and the stock downpipe is very restrictive!
