Less $ is better. I had a full turbo back exhaust and TIP fitted at the same time, so it made a big difference (earlier boost and quicker spool) I'm happy with it. After you see all that comes out it's a lot simpler and neater, the stock downpipe and associated pieces can be heavy and bulky. I've spent a fair bit on my car so it wasn't much thought to get a DP and exhaust really.
