No mods thus far on the car. I'm adding techtonics downpipe and test pipe with stage 2 Apr chip. Wondering what the total hp gain and whp will be after its all done. Money and issue so ill be putting on a cat back exhaust system in a couple months.

All being done cuz a pre-cat is going out and this will be about the same price as the stock part and replacement through Audi.

 

Just clarifying it's an 01 A6 2.7T Manual

 

Most of the stage 1 chips quote 318hp, so with downpipes you might be looking at 320-330. Don't forget to upgrade your diverter valve and throttle body boot. Also, while the MT6 is stronger than the tip tranny, you can still lunch an older clutch very easily. I chipped mine at 75k and had to replace clutch and FW at 85k.
