Are these downpipes too good to be true (ebay link)
 

I was looking to get a set of piggy pipes, but these seemed pretty great for the price ($211) http://cgi.ebay.com/97-02-AUDI-S4-B5...item2c5639dd97

What do you guys think? I know shipping would be at least another $50-75, but it still would be cheaper then piggies....

They have no cats so unless you have a tune that will code out O2s or know how to grease the man, you won't pass emissions.

The pic shows it comes with both cats and test pipes

I've seen these before popping here and there on ebay. Stragely it is always different seller selling these probably b/c they don't exactly fit or work right, as almost any knock off chinese part.

I believe these are "pretend" cats of at least cats that will have a whole 0.0000000001g worth of chinese platinum in them that occurs naturally in their "SS for 5minutes" SS alloy ... regardless.

You will get CEL immediately since they surely don't have pre-cats and the bungs are in wrong location to avoid CEL without front cat's installed. Part of price you pay for VAST piggies is for re-welding rear O2 bungs to location behind main cats so that the CEL can be avoided.

every place ive seen those downpipes, theyre listed as resonated, not catted. i dont like the 'joints' on those pipes, so i opted to go with diy piggies

sounds like I'll be doing the diy piggies...how long did it take you to gut the precats once they were removed from the car?

those are SSAC (ss autochrome) downpipes.. copy of AWE ones.. tons of info on here and AZ&QW about them

it was a MAJOR pita. i havent had them welded back up yet, or put them back in, but it was a lot more work than i was expecting. and i used air tools. i ended up cutting them. was much easier than doing the non-cut method. took me about 5 hrs just to remove the d/ps. if/when you cut, use an engraver or something to scar the metal. marker will not stay
