Although the pre-FL PSE was dizzed A LOT...IMO it is one of the COOLEST looking exhausts ever!
Although the Eisenmann Tip, which I have installed looks super classic racer and I haven't seen a bigger single TIP yet, I would switch it for the pre-FL PSE.
On my to do list incl. working valves...Klappenauspuff
Soundwise not a big improvement (and tbh, I like the sound of my old untouched muffler)...but that look...drool
Really don't need more sound, especially when you have desnorkeled and a race filter installed...you won't hear the screams of your passenger anymore @ 5000rpm
