I want to buys dvs for my s4 but im having trouble choosing, its between baileys, forge, and evo. What sounds the best, last the longest and do you have any problems with any of them? I really appreciate it.

 

If you want to save money 710n ecstuning.com $88 or Baileys $164.95each thats x(2) if you want to spend the money. I just bought my2001.5 S4 and put in 710ns the day i got it home they work great not sure about the sound although I'm always driving

 

yeah i have 710ns in my car too they do there job. as for the sound the dvs use a close loop system so you will really not hear them at all if you want a bov that you can hear get a evo or sti. if you want the best dv but get the new R1 by APR they are about 300 for the pair but they are the best. dont worry about the sound to much if you ever upgrade to ko4's you will hear the air getting sucked in more if you like that sound.

 

just bought bailey's so i hope that the R1's aren't better...! I'll know how I like these I guess when I get around to installing them.

 

yea, i thik you made a good what you have will be fine, hell mtm used 710n or was it 210's on there 520 hp car and those are the cheap ones. anything other then the 710a's will be better from what i see.

 

got them today, installed in under 30 minutes, the drivers side was a MF'r to get back on, stupid dipstick in the way. Then did a quick blast up and down Braddock Rd and it cured my issue. I could tell that in second around 3500 it would spike and lose the spike of HPinstantly. Now it spikes, and you can tell that the torque is slowly disappearing as I reach redline... works for me...

 

yeah they are on of the easy ones to get on, jstu wait till you have to put on the bipipe, if you get it. dont forget to mark on a wall where your head light was pointing or it is all trying to flag down airplanes like mine was. yeah but i think my next big spend will be new intercoolers and a rs4 oil cooler.

 

I have the Forge polished aluminum diverter valves, and get no extra noise. but a friend of mines TT has the 710 and it sounds pretty good, not rice, but good. will they sound similar in my B5 S4 or is it different because he is the 225 with the K04

 

yeah i really cant say to much cause of how different his car is. i know i can kind of hear it over my v6 and borla i hear more the sucking in of the air, after i did the darintake. i like not hearing teh bov sound cause people dont see your car being that fast with out the bov sound for some reason.
