If you want a great sounding blow off valve for cheap, I would recommend the following:
1) Locate the Throttle Body Boot
2) Jab a hole in it with a knife
3) Experiment with the size of the hole to get the desired sound
This method is just as reliable as using any of the other BOV's that advertize for hundreds more.

 

Just whistle really loud whenever you shift [sm=massbounce.gif]

OMFG, havent been here for a few days and all of a sudden theres 5 blowoff valve threads!

Must be " Blow Off Valve " season again!

Been here bout a year now and last years " Blow Off Valve " season wasnt this nuts!!!

Can u actually close the hoodproperly with those BOV under there?

If u gunna put those BOV on u car, try putting some rice in there & it will sound heaps louder[sm=badbadbad.gif]

 

This must be the 10th BOV thread I've seen this week. Either people do not know how to read, are too lazy, or cannot STFA!?

2k S4 has it right... THE F'ING CARS ARE NOT DESIGNED FOR IT!!!! Just drop it, or better yet: "Why don't you just spend the $800 and let us know how it goes...(2K S4)"
