We'll the Header test was a success and is finally over. We are going to compile the data this week and release the results ASAP. For those that are waiting to see how their header did, don't worry all headers were impressive and very comparable. Ryan, thanks for the use of your ITR, it proved to be very strong. The baseline on his car proved to be 176 hp/119 tq, very respectable for a fairly stock ITR. The highest header reached a peak of 190 hp and the lowest was still a respectable 185 hp. As you can see we will have to resort to laying out the data to see which header performed the best throughout the powerband.
