Leaving Skid Marks
An example of the benefits of an unrestricted exhaust system.....
Firstly my Legnum has 2 1/2" tuned length downpipes into a 3" system with a highflow cat and Varex muffler. After fixing leaks in the y pipe set up I decided to adjust the HDI EBC. With I went for a run with the Varex closed and settled on 13psi. Then I tried it with the Varex fully open, I was surprised at how much quicker it boosted and hit boost cut at 18psi on the same Ebc setting. Im now using both the high/low settings, one each for Varex open and closed.
