Well, I do hope they remake them and you get your hands on a set. They won't disappoint.
I'm looking hard at the Injen catback. The man at ACI says the price is supposed to jump up to $944 per unit, so now's the time to buy. Unfortunately, being Canadian, I'd take it in the teeth on shipping. They say $825 tax-in to my door. It's a lot, but at least you have the piece of mind knowing you're paying for a well developed product that will deliver.
