Don't need mega HP, and having just enough to leave a stock M5 behind is plenty. And after the cat free downpipe is in I can decide if an aftermarket exhaust is even necessary. The stock muffler tone may change considerably with the cats gone.

That is exactly my thoughts, it will come soon enough. I guess the fact it is a slightly cheaper option means people are pushing the full systems before looking at this.
