I have a few systems in stock from the same manufacturer (made in china, sold super cheap to the trade for bulk orders) bought them as a test to see the quality.
They have never been sold as the quality just isn't acceptable. I gave one away as a freebie to an owner of an Evo 9 that was in for a dyno test, it lasted 4-5 weeks before the innards of the silencers fell apart and rattled, then the wadding was being blown out of the exhaust, in the dark it looked like sparks flying out of the tailpipe!
If you want looks, try a local exhaust manufacturer as they will remove the old tips from your stock system and replace with something more attractive.
