So I've heard about the power gains achieved by many B6 S4 owners using various exhaust and down pipe combonations. Many of which totaled around 30HP and 40lb-ft. Just curious if anyone with these types of mods has taken their cars to the track and what kind of times they were running 0-60 and quarter wise. Numbers are great but if i'm not going to see a noticible difference I could use the extra $3K when I go away to college next year. Thanks in advance any help greatly appreciated!

 

chirp...chirp... Anyone?

Looks like 18-19 hp and trq plus race gas option/stock/valet and flash loader
Worth $1grand?

I don't have the B6 and have not had any experience with a modded one, this is all I can report.


Hmmm, both give you at least 42hp and 43trq without race fuel program for approximately $4,000.00, not bad.

 

thanks hadn't seen those systems before, however chip or flash are both out of the question until my warranty is up.

 

What about this one from APR then?

The APR doesnt put down quite as much power as the milltek but wow a grand cheaper. Now I just have to talk to the dealer and make sure they will service my car under warranty with it installed (maybe get it in writing) then the hardest part, convicing my dad to le me do it, and coming up with an excuse to explain to my mom how my car has suddenly become louder.

 

it should be fine with the dealers, if its cat back there are no warranty problems
thats what my audi rep said
mom wont notice if you keep the revs down and no full throttle near the house
just tell her your breaking the car in
