I don't have a dyno sheet or anything to show you but can say that it is a very noticable difference in power from the stock components after adding my long tubes. Plus that's the only mods on my engine. You will love them if you get them.
The install is a bit of a pain, but it's not all that bad. Once you get them installed and fire the car up for the first time it makes it all worth it.
I know I probably looked funny as hell driving down the road with a huge grin on my face driving by myself during my first time out with the new exhaust, but I couldn't help it =)
