I had one of these on my .2. Great sound and still looked to be in excellent condition when I replaced it with a set of Dundon street headers. No signs of deterioration on the exhaust. Took it off the shelf to take a few picks for an interested party a couple of days ago.
For simple mod to make the car sound a lot better it's hard to beat.

Sound is amazing, and is completely tame with valves closed / non sport (she didn't notice anything on a 30 mile ride today with valves closed), but with valves open it just rips. It does make the tone of the car very slightly lower than stock, much louder than stock. Sounds great idling now with valves open and had a friend do some drive-bys and cannot believe how loud the car is (easily hear it a 1/4 to 1/2 mile away on acceleration and downshifts)...can't imagine this thing with side and rear deletes...regardless this is perfect for me, extremely pleased. Figured if this was too loud then I would put the Shark Works on, but the GRP is staying put. Also want to give a shout out to the guys and gals at GRP who sent me 4 new install clamps and their customer service is clearly responsive, and top notch! (coming from someone who bought a used exhaust not from them). Mine is for the 991.2 so the tips do stick out but I like that look and perhaps less soot on the bumper from the rear vortex (well who am I kidding with that) and the diameter / slant / size is perfect, looks and sounds purposeful....in addition it leaves just enough space around the tips and the rear cutout to still look proportional to the car...realize I'm a couple of years late to the party but happy to be here! Would recommend this exhaust to anyone without hesitation considering replacing the rear muffler.
