It replaces the exhaust just after the downpipes. The two factory cats in the downpipe are still in place. But the secondary cats, along with a bunch of bendy exhaust tubing, was all replaced. If we can make good power with this quickie exhaust, we should do really well with a production version offering larger volume mufflers, mandrel bends, etc,. In a way, I wish I had waited to put on the exhaust later and just re-dynoed the car with just our new-found fuel and boost control. But I didn't. So shoot me. We could always stick the stock exhaust back on next week and dyno it again. But hey, I was impatient for a fast car that actually sounded fast"
