Have talked to one of the best tuner in Sweden to make a step 1 software that also has extra "pops and bangs".
There would be no problem at all.
But according to them, I will have trouble with the catalyst. "Pops and bangs are badly injured on the catalytic. So shorten the life expectancy ..
It will already be of major problems with cars that are original with "pops and bangs" like RS6 etc ..
So what do you think about this? 
It's unburnt fuel detonating in the exhaust so yes, it's not going to do the cat any good.
Sounds cool though! There's a Mini Cooper JCW just up the road from me that has the sports exhaust, it sounds great
