Yo whats up everyone..I am new to the forums...I just bought a S4 last Monday and am in love with it...I have been constantly looking at exhaust, intake and the DV are new to me. I was used to BOV. Please help me and guide me in which direction to go first. And also a short shifter. I just got the windows tinted, I will upload pics soon. Let me know Thanks Mike

 

well id personally say a chip first.. also waht year is yours.. .. good companies.. awe, apr, asp, mtm for tuners.. exhaust.. labree, awe, milltek, or aprs.. skip on the intake, there is no gains there.. bailey makes a good dv

 

For a short shifter try VastPerformance.com... I personally prefer OEM Audi 710N Diverter Valves. For chips, there are plenty of choices like Sooks mentioned, do some research asnd see what fits your needs the best. In my opinion, GIAC=most power, MTM=great power, but very smooth and APR=most options. For exhaust, there is also borla, probably the most inexpensive of all the choices but still offers the same performance and great sound.

 

its a 2000

 

Just like my car....

1st maintaince! make sure everything else is ok.
Check the TBB & Dv's they don't like boost if there on the way out.

Chip is the way to go, pick what ever one is close to you, there all around the same.
