Anyone running the Borla XR-1 race mufflers on their V?

Ran one in my first project...LOUD, very LOUD!!!

Worse than corsa, even with resonators and packin, they resonated too much noise inside the car...

You have plenty of other options, stick to them and have fun...

Which XR-1 were you running? There are multiple sizes and shapes.

I ran XR-1 (I think it was the sportsman) race mufflers on mine before, sounded very nice with an x-pipe. Only reason I took them off was for a B&B upgrade.
I didn't find them loud enough.
I used to have XR-1s, and now have ProXS mufflers on my Mustang with long tubes and a Dr. Gas X-pipe. Not sure how much difference there is between the ProXS and XR-1, but they both sound fantastic IMO. Plenty loud in my case, but that's partly due to the resonance created by the long tailpipes after the mufflers on a Fox Mustang.
