It's not a true "turbo-back" system. I bought the GHL full turbo-back stainless exhaust which includes a sweet stainless S-pipe as well. This is a good price for what is being offered for sure but if you want to free up your exhaust completely, the GHL turbo-back is the cream-de-la-crop! The S-pipe on the GHL system is much less restrictive and provides a smooth exhaust flow to the downpipe instead of the sharp bend the stock Callaway S-pipe provides. Like I said, this is a great deal on this Vibrant, this is almost what I bought but I wanted the S-pipe also and I don't like Corksport's. I love mine... sounds meeeeeean, and is!
