Apexi Exhaust Control Valve

[pakuadragon]

Just installed one on my car with SR20det and got to tell everybody how well this product works. First of all it quieted my car down to almost stock sound, this is with an RSR ex-mag. I know many people say that the RSR is quiet but not to a cop who just recently pulled me over. It must have been my lucky day because he let me off with a warning. I took this as a sign and decided to make the modification. It is basically a test pipe with the control valve welded on. The version I have is the 80mm version which is a weld only type. Just wondering if anybody else has this installed on there car with same results.
