piggie pipes?

[mthomas141]

How much HP do piggie pipes give you? My car had the exhaust and chip removed an I am just wondering what the piggies add. I also have my post 02 sensor go bad where can I get one for cheap and how hard are they to replace?

[raketeS4]

i felt that doing piggy pipes was more beneficial in helping my turbos spool faster, rather than in adding horsepower... i'd say maybe 10hp?

as for your 02 sensor question, i have no idea

[YZracer]

i heard around 15, but you won't feel much extra power, just a lot faster turbo spool

[Das General]

get the cb and ecu back in, then slap some piggies on.

what is the dif. from piggie pipes and down pipes ( ex. autospeed ) ??? pics ?

[Quikslvr]

20 hp with a chip and 10hp without + less turbo lag and you can hear your turbo more.

piggies are dp's, they are the stock dp's gutted.

[Quikslvr]

They are stock down pipes that have the first set of cats gutted. They still have a set of cats so you can still pass emissions. They are the next best thing to aftermarket down pipes.

Replace your rear O2 sensors with the ones from VAST. They are top quality. It's not a tough job to do, but routing the wires is a little bit of a pain. Just make sure they clear any moving or hot parts like the driveshaft and exhaust pipes. You'll need a 21mm or 22mm open ended wrench and some zip ties. Make sure to check the existing wires for where they clip to the tranny and follow this path for the new wires. I did it on a set of ramps.

Also, just clear the codes from address 35. Nothing to worry about.

[mthomas141]

which ones do I order from vast?

you order the rear o2 sensors, just go to vasts website and take a look its pretty self explanitory. Or call them they are friendly guys and are willing to help you out.

piggies don't add a tone, but about 10-15hp

[RxDlr]

how do piggies not add tone? I thought that there were a few people that had said they experienced a more full tone after they had freed up the pre cat's, correct me if i'm wrong but i'm pretty sure i read a few people that had posted that

[mthomas141]

oh yea they for sure make the turbos louder it sounds cool! my mom thought that a cop was behind us when they began to spool

[W1CK3D]

So you heard a siren? Uh Oh...

[Das General]

they do. turbos spooling and the exhaust, if you are def they might not add a tone.

[Renegades]

oh yea they for sure make the turbos louder it sounds cool! my mom thought that a cop was behind us when they began to spool

And how loud was this..."siren" noise??

[AB18]

Vasts site says 20-30hp gain if your chipped.

[mthomas141]

it was just the spool of the turbos at about 2k rpm. under wot there is no turbo noises that sound like a siren

Ok good to hear

whoops i didn't mean tone, cause it does chance the tone of your exhaust...i mean tonne like it doesn't add alot of power. my bad.

[Gigi]

I just added VAST Piggies.
With stock exhaust, sound is almost like stock. Catback opens it up.
Power wise, I feel a big difference in trh elow RPMS, more torque. I heard #s like 20hp and 30lbs with chip. I would say it seems a little lower but the car is a lot more responsive starting b/w 1500-2000 rpms. Can't wait to get the catback !

You did your dps with stock exaust still on? Wow I don't think I've ever heard of someone doing that...are they easier to swap on an A6?

[mthomas141]

no that is how the car came.

[RuS4ty]

I cant wait to do piggies, but I cant imagine my turbos being any louder than they are now (without being blow). Mine are pretty damn loud when I get on it... :/

I think you mean a ton...

[Gigi]

yeah others have done it, I mean they are the stock DPs after all! VAST just works their magic on them :)
At the time, I could not justify dumping that much cash on an exhaust that adds little HP... mostly sound. Instead I decided to put my $ toward shocks and DPs that do add power. But my shop tells me he might have APR catbacks on sale soon so........ :)

[DoGGRoBBer]

Doing Piggies, is a great idea, it opens up the exhaust, lessening the restriction on the turbos. Faster spool up....less wear and tear on the little K03's . 20-30 HP is a bit high IMO. But the little money invested will prolong the life of your turbos..... They flow so much more... the first cats are so restrictive( like a cigarette filter) I had mine done by 2001S4NY (great job, BTW) and added a MBC. I'm now running about 18-19 psi and peaking around 21psi....running great on an old T.A.P stage 2 eprom.... Pulls like a CHAMP....


Thanks Again Greg.....

[tonggi]

I have 2 OEM Bosch 02 sensors. I will sell them to you for hte price that VASTs wants if you want.

PM me i fyou are interested

[mthomas141]

so if you go here:

http://replacement.autopartswarehous...Sensor&dp=true

it has like the universal ones at the bottom for pretty cheap what do you guys think?

[AB18]

Now im thinking of just doing this, at first i didnt want to because of how much of a pain it is to install them, but ill just get a buddy to help me out. What all is needed from vast to do the job other then the piggies? Im kind of in the dark here as i haven't looked into much. I know i have to relocate the 02s, can someone elaborate more on it? thanks guys.

Does that write up involve any welding? Because I know that the write up on DIY Piggies on AW involves cutting open the pre cats and welding them. Is there anyway to avoid welding?

[updaboost]

My pigges add a tone. And they relieve stress off ur turbos. Should make them last longer. Im happy w mine

I think the writeup is for not cutting the cats.

Its harder to do it without cutting the cats but if you don't weld or have a machine then it would be the easiest choice.

[switchface]

IIRC 2001S4NY has a clip on his site of a borla exhaust with before & after piggies. I can hear the difference, not louder, but the tone sounds more flowing and aggressive. Piggies are on my list...

[nogaroblues4]

Hmm maybe I can do my own piggies without welding then if I can ever get a hold of my mechanic friend that has dropped off the face of the earth.

[tim]

10ish, if that?

[mthomas141]

anyone got an answer on that website i posted with those 02's

AB18, there is a group buy right now for s4 coilovers on this forum.
