Test pipe

Hey guys...I don't know if any one saw the test pipe for the MX3 on ebay, but I saw it a while back, and I decided not to buy it, but now I'd like to but I can't find it!

Any one know where I can get one?

I have another q about the test pipe too. I've heard that on some smaller engines, straight pipes, or a test pipe, will cause you too lose hp instead of gain hp...is this true?

I guess this means that no one knows anything about where I can get one?

they often sell on probetalk..it's jsut a piece of metal tube with 2 fllange you know...don't know if the probe TP will fit the mx3 without any mods but it'll be the closest...changing your cat for a testpipe is a good idea if you're changing you cat-back..but i guess it won't do much if you just change the cat
