Hello

I want to know peoples opinions, especially if you have tried both on your 350Z, about Cats vs Resonated Test Pipes. Which will prefrom better and give you a better exhaust note? I'm staying NA all the way so I want to choose between Cats or Resonated Test Pipes for my 350Z. I would like to get a nice sound out of this mod to add to the gr8 exhaust note I am already getting from my Greddy Evo2 cat-back exhaust.

Also any takes on the new Plenum from kenitix? it looks really well done:

thanks for the info!

 

Hey buddy, I saw your question posted over in the main Z area, and you were pointed over here and still got no answers. I'll tell you its mostly because many people have asked this topic before. If you do a search for test pipes you will get a list of topics. This is one i found Test Pipe Topic
Sometimes people ignore questions like this b/c its easy to find the answer in a search.
Good Luck

Most experiences I've read and had with test pipes and HF cats is that they negatively effect the sound as the stock cats are "tuned" from the factory to eliminate unwanted noises like rasp and hissing sounds when decellerating.
