I went to the turner shop a few weeks ago, they have a Racing Catalytic Converter and Racing Resonator, i guess there high flow parts, anyway with those 2 parts and a high flow muffler, they was like I would need an O2 sensor regulator or summ'em like that, can't really remember. Maybe someone can give me more info about this. Also, I hear that most of the engine upgrade have to be installed with the engine lifted, I dont really wanna do that. Is there any other parts I can install without lifting the engine?

 

IMHO, I'd stay away from screwing around with the exhaust system. It can run into a lot of expense for very little performance gain. If you want to get the biggest hp increase for the least (relative) money, install a performance chip along with heavy duty diverter valves and throttle body boot. Do your homework on the websites first: GIAC, APR, etc.

I think we had that discussion with you already.

 

You may have, I kinda wanted to stay away from anything that will viod my extended warranty, I ask awhile back if the chip would void the warranty, no one responded, so I was kinda lookin at other upgrades. I'm thinkin about just running stock because I cant really find the answers I'm lookin for, and the help.

Besides the chip, what dose people usually get done to there Audi's, I onld had the car for a month.
