Quality product from a QUALITY ZR-1 tuner in the US!!!!! Bonus!
As far as saying OBX / Stainlessworks headers are going to give you far less "RWHP" or MPH (in the quarter mile) is doubtful.
Brad is comparing two different cars and not the "same" car. In order to get a true comparison, you must install OBX/Stainlessworks and dyno the car. Then uninstall and reinstall Corey's headers and do the same test.
I have StainlessWorks headers (relatively happy with it), but if Corey was making his a few years ago.... I would have purchased his!
Love to see a "true" test of all of the headers....

i am sorry maybe i didnt write it correctly . the comparison was done on the same car . i took the headers off the 90 as the head gasket was blown on that car and put the jeal headers on the 92 . the power difference was to the 92 car . it made 17 wrhp more and 6lbs of tq more with the jeal than with the stainless works /obx design . all dyno runs were done on the same dyno on different days.also it was just a little warmer on the tests with the jeal headers . we did 4 pulls on both tests . all pull were within 4wrhp of each other .the only change to the car was changing the headers , i used the same exhaust that was on the car and didnt do anything in the way of tuning the car . it allways buged me that my 90 made more power with just with just headers and inj housing and plenum porting than my 92 which is a callaway 475 super natural . this motor has ported inj housing plenum and heads ,as a part of the callaway 475 pkg . next i want to put coreys ported inj housings and plenum thats on the 90 on the 92 and see what the difference is .
