I have the sts kit with a tail bov. I wanted to buy the loudest one they make. Who makes a loud BOV and if I were to change the bov will it affect my tune from the dyno. Because I just had my car dyno tuned to run safe 5psi of boost. I just dont want anything to affect the tune. Let me know - Mike

 

I have seen a million posts like this one honda-tech, however, this is the first that i have seen here. Get the turbo xs blow off valve, it stands for really ****ing loud, http://store.rms-usa.com/blowoffvalves.html now while your on the site dont forget to check out the aluminum wing section.

 

If you want loud, go with a turbosmart megasonic. The TurboXS BOV's are subpar in quality. Main reason why we dropped using them.
