On the very early RAM cars, the stainless systems were pretty stout. Mine probably had at least 50 track days on it when the header cracked in the collector weld. Even then it would not likely have failed with the cat bypass pipe, but I was testing a new type cat for Brammo which failed big time, totally blocked the exhaust flow and split the header. On the other hand, my red car (vin ending in 100) had a really inexpensively made pipe which split on the third track day with no cat in place. If you have the stainless pipe and do not plan to track the car slot, it would be worth the fix that Silver mentioned. If it's not stainless, replacement would be much better. I ultimately had Tom Smurzynski build a top notch modular system that I love, but before that I had Brammo replace my busted pipe with a stainless unit like my RAM280 car. It never failed, but was too restrictive, especially after swapping in a Harrop supercharger.
