So I just bought downpipes!!

[chrisbostonusmc]

For 50 bucks

What a steal.. Hours of browsing on ebay have paid off!
They look like good quality, What do you guys think!! You can zoom in to see the welds also!

I have them on my car. They are perfect for my stage 3 setup since there are no cats. Just a few things to note:

A. They might not work on a tip car since the tip downpipes have a different shape.
B. They are made for an S4, so you will need to cut down the longer side and weld the reduced end back on.
C. The wannabe Aeroquip clamps are not easy to align and tend to leak.
D. Holy turbo spool Batman!

i wish 4.2's DP would cost that much

[white fish]

is it the whole exhaust?

Do you have the exact same ones, because these say they are specifically for the A6...not an S4.
Also if you do daft, should I just weld everything and forget the clamps?
6speed for the win
also who makes these??? I bought them out of michigan
Thanks Daft

From the looks of it, it appears it ends with the resonators

These were a lucky find, due to a process on ebay called selective typing...i.e. instead of typing s4 downpipes which will have alot of views, I type A6 downpipes, not many people are gonna look for those. If the buyer put s4 downpipes, they might have sold for more

damn 100$ shipped that's good!!
ssac ftw! :)

[sempaipaul]

HLY S**T THAT IS A STEAL!!!!

if only they would fit a tip :/

[Kievskiy]

looks like SS Autochome system, i have them on A6, DPs only, forget the clamps or do better clamps, overall the exhaust is not bad at all

nice deal, grats!

Chris,

They are the SSAutoChrome downpipes. They were never made for an A6, only for S4 2.7T cars.

The kit includes both a set of the resonator sections and the straight pipe sections. The resonators have secondary O2 sensor bungs. The straight pipes do not.

I will say that even if you plumb the O2 sensors into these pipes and even install de-foulers, you will still get the CEL for the main cats not working. The problem is that you will have no cats at all now and there will be zero reduction in emissions. The secondary O2s will not see a large enough delta in the readings from the primary sensors and the ECU will think that the cats are failing.

Anyhow, I ended up having my software guy turn off the rear O2 sensors in the ECU and now my CEL is gone.

i have 2 defoulers on each side on secondary sensors ;) no CEL for almost 2 years, well i had CEL but only for misfiring, CEL was gone after better spark plugs :)

like this Kievsky?did you have foulers on all of these?

I'm surprised. Mine wouldn't go away.

Chris, you would only use them in the secondary locations where the resonators are. The primary sensor locations should always be plumbed directly into the ehaust stream to ensure proper fuel trim adjustments.

nice deal. Good luck with them. Are you still in the carolinas

I will be pm'ing you for help when I install these in a couple of weeks( I have access to a welder and lift!)
I will post pics also

Just curious what would a shop charge for install? I have heard horror stories with installing dp's

nice deal. Good luck with them. Are you still in the carolinas

Thanks! Yes I am still in Eastern Carolina..
kinda bummed we didnt get any good hurricanes this year... :-(

[oc-drop]

wow

[oc-drop]

even crazier is that the same auction is now $350!

hope you get them!

[Kievskiy]

to tell you the truth Brett, i am still surprised, knock on wood, but simply 2 defoulers, aka spark plug extensions, working perfect for me, i had idea that maybe 2000 had simpler electronics in that area, but for like 10$ for all 4 defoulers its worth a try, cause i am sure to recode the ECU is a lot more.

Did you remember exactly how much you had to cut-off??

Would it be easier to cut the exhaust rather than the DP?
Since the car will be on a lift with a blow-torch and all
