what kind of chip do you guys suggest to get and where can i buy one for a good price, car is completely stock and im looking for a nice HP gain. so i figure chip is way to go!

 

to get the best gains out of a chip get exhaust and a diverter valve also as for brands do a serch on this as this has been posted mutiple times and everyone has different opinions

 

Chip:
APR
GIAC

Both have about the same HP/TQ numbers. APR is smoother and provides more HP but GIAC is said to be more "aggressive"

If you have a 01.5+ you could also get REVO. Alot of people seem to like it.

Exhaust:
Borla : 2.25" Piping
APR : 2.5" Piping
Neuspeed: 60mm equates to 2.36"
Miltek: 2.75" Piping

APR is about $900
Borla is about $650
Miltek i think is around $700 ( I may be wrong)

DV/BPV (Diverter / By Pass Valve)
710N: Stock part on newer audis with upgraded diaphram
Baileys
Forge 007

In mid boost application the 710N will preform just fine. Its about 30$ at the dealer
For higher boost applications the baileys/forge will hold the pressure better bust cost around $100-150


This information is for B5 models. If you are a b6 the answers might be slightly different.

Let me know if you need more information

 

small edit for you insane neuspeed exhaust is 2.5 not 2.25

 

yea sorry about that for some reason I thought I saw a Neuspeed that was 2.25" On the site it says 60mm to 70mm with 60mm being 2.36 and 70mm being 2.7" roughly.

 

Sry to jack the thread but clconversion i see that you have a nuespeed exhaust i was wondering how is it? how does it sound? is it louder than the borla? does it have a deeper tone?

Thanks and sry again

 

hey it sounds ok at higher boost levels it kinda wistles sorry I have never heard a Borla system
