01 TT Quattro 1.8T Downpipe Advice Needed
Still running with the stock turbo on an '01 Quattro 1.8 (for now) and the flex joint on the OEM downpipe has severed completely from the flange.
After some creative welding, she is temporarily running, (just for warm-ups and around the block driving)... until I can get the part.
I need some feedback and this forum comes highly recommended.
I bought this car to tune it, and have been building a list of performance parts, my question is related to engine compatibility comparing the TT Quattro 1.8T with other VW 1.8T's.
(IE: A4 ) I assume that the Audi name lends to possible mark-ups in price, since I have found dozens of different downpipes online ranging in price from $100 - $1,200.
So my question is: If you were me, where would you get this downpipe (would prefer without CAT).
Reminder:
01' TT Quattro 1.8
Manual Transmission
Stock Turbo
The rest of the exhaust from the cat back to the tail is fine (though it's high on my list for upgrading now)
I only mention it because if this were you, you should know that you plan on upgrading the exhaust system within the next month so that might change your decision as to which downpipe you would buy.
Thanks in advance for reading my post and any direction you could point a new Audi owner.

i put the 42dd downpipe on our TT (225 chipped) and it felt like I added a second turbo! Was quite amazing what just replacing the dp did. Not the easiest install.. but can be done.
You MUST replace all your engine mounnts - engine, trans, and dogbone. or the engine will torque and the pipe will hit the body, then the driveshaft..over and over.. I went with the poly mounts. work great! Located the engine quite nicely.
Don't think about doing the job without doing the mounts.
Also, you will likely pull 02 sensor codes. Space the downstream sensors out of the stream and it will eliminate getting the codes.
Also replace the o2 sensors while you are there. There are cheaper alternatives that can be installed and work.

Good advice on the 42DD. Mine has been in for years
without incident. Good advice on the O2 sensors too...get them from Amazon nice and cheap. I just replaced mine today. Get an angle block for the post cat sensor to eliminate any CEL's. MCPi has a nice one..http://www.mcpii.com/engine.html.

I've been looking for the parts numbers on amazon and on the forum as you mentioned and I cannot find them. I would prefer buying anything I can for the car from amazon.

bosch 16109 for pre and post cat. The rear one's wire will be a bit short, but if using the spacer mentione above, will fit perfectly
you have to search this forum for the part#. It is not in the book or cross ref.

If I eliminate the CAT (as I plan to) before upgrading the cat-back section for a wider diameter, won't the downstream sensor (after CAT) fire off codes with the CAT gone?
Also, is there any reason to upgrade the tail of the exhaust system (performance reason) to a dual exhaust system? Some of the aerodynamic body pieces I am looking to fit onto the car have the space for the dual exhaust tips.

Oh, I just realized that Black BeauTTy answered my first question lol, I hadn't even noticed that post.
I would be most appreciative for an answer to the second question however, of course. =)
