Motordyne ART Pipes
 

So I was thinking about getting the Motordyne ART pipes because all of the videos I have seen, show it as providing a very deep, bassy note to the overall exhaust tone. That, along with the numbers on the HP and Torque gain that I have seen make it a very promising CAT replacement. My issue though, is that of all the test pipes I could get, they are easily the most expensive being up to even 3x as expensive as other brands. So my question for anyone who has it, as well as others who have already replaced their CAT's with other brands, what do you guys believe is the best bang for buck? Do you think I should just cough up the extra money for the ART pipes or go for something else?

Definitely worth the money. No rasp. Helps with drone.

+1 If you are considering test pipes for your Z the Motordyne ART pipes are definitely worth the coin. The Motordyne ART test pipes have a unique sound to them and produce a deep tone with no rasp noise to them also with reduced drone. The only other pipes I would consider are the AAM test pipes.

I had them and they are ok. Not worth the price new. You can get used ones for a descent price. They are prone to cracking.

There is a guy on facebook, James cworksdesign, that makes and sells the same things but for $495 shipped. He's the fab guy who makes admin's intakes.

I had a full Motordyne set up up on my G35 and when I sold it and got the Z it was one of the first mods that I bought. Good sound and quality in my opinion. I made a video with the set up I had on my G.
