Default 2007 Grand Prix GXP Exhaust - Tail pipe w/ dual tips

Has anyone done an exhaust replacement on their 2005-8 GP GXPs? What did you use? I really like the look and sound of the original tips (below photo) but the original GM part 25794074 is discontinued.

That 25794074 included both mufflers with the attached dual tip tail pipes, and the exhaust pipe. See: https://www.gmpartsdirect.com/oem-pa...lpipe-25794074

After researching potential systems for the GXP and checking with a local repair shop that checked their exhaust components sources, I found that the Magnaflow 16726 Stainless Steel System was probably the best choice if not one of the only choices. Interestingly, Amazon offered it at a significantly better price than the big auto parts vendors I found.

It is not a cheap system but the quality looks good and I plan on keeping the GXP for many more years.
