I am planning on going to "test pipes" next month with a tune. I have heard people talking rediculous gains for such a simple mod. We will see. I am sure it is going to be loud as hell with my current setup of fabspeed xpipe and Megan Ti race exhaust. I have even contemplated putting electric exhaust dumps on the tail end of the test pipes to run as close tomopen header as possible for those time when you just want to bask in the symphony of the V8 at speed
Something a little like this
