Invidia 70mm test pipes, HS00HS1TP2 or HS00HS1TP3

[Red Stwokay]

I'm finding both available and wondering if anyone has used both. The HS00HS1TP3 can have an external celfix added cheaply, some are offered with it. The HS00HS1TP2 has an internal celfix.

The external celfix looks pretty basic and rugged, the internal is hard to tell how it is made and constructed. In this one the seller says it's an HS00HS1TP3 in an email reply but the picture is of an HS00HS1TP2. This is a good picture of the internals though. Invidia's site doesn't have a good picture like that. http://cgi.ebay.com/ebaymotors/ws/eB...m=330244764231 Here's Invidia's site http://www.invidia-usa.com/Products.aspx?CategoryID=15 scroll down to Honda S2000 00-UP 70mm test pipes.

What I'm wondering is which works better, which holds up better and will both pass emmissions testing? I'm guessing the pipes with celfix should pass even a visual because they will have the sensor attached and some of these pipes are advertised as and called high flow cats. The big issue is when they hook you up will the scanners say all is well. Don't want to have to swap pipes for emmissions...

I don't know which is better, but I can tell you none of them will pass visual inspection!
