I found out that the XR-1 is still stainless steel packed like the rest of them. The multicore race XR-1 some how flows better than anything though. The sportsman XR-1 is just like the others and the magnaflows.

Borla may perform slightly better, but Magnaflow's are cheaper. Also, what Magnaflow's are being compared to the Borla's? I'm betting that Magnapack's perform the exact same as any Borla. Sound-wise, it's purely subjective. One thing sounds like a masterpiece to one, but to another, it sounds like junk.
