I have never done A - B testing on the stock 07 upipe

The stock unit has no cat - however it is somewhat restrictive and a aftermaket one is going to free up air flow

One day we will have to do a A - B test to quantify any gains

With the stock air box and TGV's in place I am not sure the upipe is contributing all that much - maybe as the customer progresses in his stages the upipe mod will reap more benefits
