After reading about this product by QTP and having it brought to my attention by Hussein's thread, it sounds like a neat idea.having the option to keep your quiet exhaust, then instantly have an open and aggresssive exhuast while giving you the power. then close it right back up!

i was just curious who else out there has this product, what are your thoughts, and what the stock piping is on the 2.5s? the smallest piping they go down to is 2.25" but i'm not sure what it actually is. i'm sure it will give the 2.5s a decent performance gain but i'm wondering if i should upgrade my exhaust setup to 2.5" if its sitting at 2.25"
educate me!!!
