ahhaha i played with this stuff like 3 years ago when i still have the TL-s. Let me tell you guys something, this QTP gona make a big ass loud ass sound, even better then those bike' muff but it will not INCREASE any horse power, unfortunately you will lose some power out of it. I bought dual for my TL, welded it on by a friend. It was working great for a month and then i got stuck. Im sure 95% u will get it stuck trust me. So trust me its a waste of money. :thumbsdown:

My Ride: 545I and a half dozen other rides
The factory puts a vacuum switch and door to open the second muffler on the 545. I've been really thinking of putting a straight pipe or short glasspack in place of the second muffler. Just to hear what it sounds like at idle and WOT. Anyone try this yet?
