I have a set of OEM downpipes for sale with gutted precats and gutted cats

[rs6queens]

If anybody is interested make me and offer.

I'll raise the lowball offer $50:) Seriously though, around $400 for starters? Not sure, but i would like to swap mine. Can VAG com clear the O2 codes, or tuner right?

[rs6queens]

The tuner will have to turn off the o2's for you. I'm looking for something close to $500 plus shipping

[colton14]

How hard is this install?

[lswing]

Tough to unbolt from turbos...and the part that I wish I could do is clear the resulting CEL since your DP 02's will be gone...there must be software out there, hmmmmm.

Edit; besides what tuners have to clear them...

[rs6queens]

It's not an easy install but end results are nice. My 02's were turned off on my ecu, never got a CEL light.

[lswing]

How/who turned off you 02's and what software?

[rs6queens]

I have a local guy that tunes s4 and rs6. If interested I can ask him how much to turn them off.

Rear of engine must be lowered to get access to the turbo bolts. Then you need to be sure not to break one. It will be engine removal if you do. Besides the extra flow, there's a nice side effect of the turbo spool sound.

[rs6queens]

I can get the rear O2's disabled for you for $50, if you buy the downpipes.

For the nuts that bolt the Downpipes to the Turbo's here is one of the gotchas. Do not try to use a 16mm socket over the outside of the nut as the clearance between the nut & the downpipe will put a bind on it, use a Triple-square socket on the inside of the nut. It is not easy to see from down below as your looking up that the nuts accept a Triple-square on the inside until you get them out.
