My girlfriend wants an A4 1.8tquattro

[1439/2000]

So is it that 1.8ts have really good flowing exhausts stock or is the turbo too small stock to benefit from a more free flowing exhaust?

I can understand a dp but the bottleneck effect doesnt change anything? Also the stock blow off valve is plastic I believe and the bosch ones that are in some porsches are metal. To me that would be a good upgrade as well. I'm still learning about the mechanics that make these how they are.

The stock exhaust is not that bad. But anything to make it breathe better is def better... But, if its just chipped with a KN drop in it will be a fun car compare to stock. Exhaust wont gain much but it will give it a nice sounds and the looks.

Give you and Idea :

My TT wich has a 1.8t with a ko4

Stock #'s Dynoed at BG

180 Hp / 195 tq

After a K&N drop in, Forge DV and GIAC Chip

Total $
Chip $500
DV $ 135
K&N $ 50
----------
$685


225 hp and 275 tq.

I havent done anything else to the car.. Looks completely stock and is fun ass hell. I think the A4 has a ko3, Not 100% sure. Still no major diffrences between the ko3 and ko4.
My Next step is a DP.. all the other mods, Im not interested since It wont do much.

stock exhaust is poop. you could get a cheap 2.5" or 3" downpipe and hook an electronic dump up ... but I would suggest a 2.5" turbo back exhast. Should be more than enough to open the turbo up.

yes, upgrade the DV. Those things are weak and break when you start modding. Companies like Bailey's and Forge make aftermarket DVs ... or you could just snatch one from a TT.
