One of my favorite mods for my GT350R. Love hearing the full exhaust note of the 5.2 Voodo all the time, cold starts are amazing!! Exhaust note in 6th is perfect. Install was easy and took less than 15 min with putting the rear on ramps for clearance.

This is EXACTLY what I was looking for. Easy install on the ground, took me maybe 15 minutes. The time spent was waiting for the exhaust valves to open up after shut-down, which took about 10 minutes. Cold starts are what they should be, and 6th gear cruising with the valves open is perfect. Thank you for creating an easy solution to a major discrepancy that Ford overlooked. 10 stars if able!
