Review on RYANSTAR Adjustable Turbo Dump Blow Off Wastegate Valve BOV 25mm – Universal Fit in Sleek Black Aluminum Design by Ben Jacobson

I have ordered two to try out my BMW N54 in place of the stock bypass valves after purchasing a vrsf blower pipe rather than using a blow off valve and 6 times had paid more. Price for a major brand name and so far they hold £18.5. I would easily upgrade the jb4 with mhd rear flash, cat free DP, bmw dual cone air intakes and a few more bolts unrelated to the performance of these. I put them in the atmosphere and they sound great with a strong deep whistle when released. The big chunk of the money they keep is the boost I spent and I bought them on a friend's recommendation with the same engine and 25psi turbos but I know they will keep that.
