TDR Waterbox.. Good , bad, different?

[jdanthony]

Hey all, couple questions.. 96 XP related..

How much is a good price for one? Buy or sell

Is it that loud?

Performance yes/no?

Does it need a rav valve like the stock one?

They are about $250 new(Tony Ducas Racing is still in business) and I sell good used ones for 150 shipped. Yes one made for a 787 will have a boss at the top tapped 1/8" NPT. They are loud and that's what people like about them. There is not much, if any performance increase especially over a 97SPX wb. There are a couple versions one with a baffle and one without. Both are crazy loud though.

They are over $200 new so anything under that is a deal. They are loud so if you don't wanna be noticed from a mile away it's not for you. You do not get any performance gains from a water box, just more sound. And yes your rave valve swaps over.
