I'm looking for a test pipe that fits. I know the 4th gen and 240sx works but the resonated versions on ebay are all made by megan or Isis(which i heard are bad) I know the 2000-2003 Megan test pipes and ebay pipes are too long. But did Megan make the 4th gen and 240sx pipes too long, or are those Megans safe to get length wise?

 

I have an ISIS, can't complain. Same length as stock, not too long like the Megan.

All 95-03 models are about the same. My old LSS TP was from a 4th gen and sold it to a 4th genner, and it worked on my car fine. Bought a Megan from a 4th genner, and sold it on eBay becasue it was too long for my car. Decided on an ISIS and it was as long as the 4th gen one that fit and the FastCat which is also a perfect fit.

How can a test pipe be "bad", it's a simple concept, the only ay you could mess it up if you make it too long or short.
