Motordyne XYZ Y pipe
Posting a Motordyne XYZ Y pipe review after about two months of it being on my car. I did not do the install my self. Keep in mind I installed this with PPE LTH's and a Tanabe Medallion exhaust. WHP results will not be accurate as the dyno was done with all exhaust mods.
Packaging: Came in well wrapped and protected in a normal brown box. Everything I needed came with except the clamp to install the cat. I bought one on my own and used that for the install.
Installation: Install was very straight forward. This was done in less than an hour. The Y pipe fit almost perfectly with the PPE headers and exactly to the Tanabe exhaust. Everything bolted up and lines up fine. It's very easy to remove the cat if I ever wanted to add an extra resonator or straight pipe.
Appearance: The Y pipe came unpolished but made of T304 stainless. With the rest of the exhaust, it fit right in and looks all business. One would be hard pressed to recognize that it did not come with the rest of the Tanabe exhaust. The welds were tight and the fitment was spot on.
Performance & sound: I can't comment very accurately on this particular topic because of the other exhaust components. I do know that having the cat helped remove a lot of the rasp and reduce the sound level of the exhaust. It definitely has no issues with flow. It doesn't feel chocked up like the stock Y pipe. If I were to remove the cat and install another resonator, I'm sure I would gain more power from the car, but I particularly think it's bad a$$ that I can run a cat with LTH's. Just having the choice to run however I want is a huge bonus and worth the extra coin.
Conclusion: I bought this shipped for around $515. For it to mate to the other parts as well as it did is a boon. Everything just worked. Having the option to run straight, resonated, and cats is fantastic. This definitely cost more than an Ebay pipe, but this is on a different level. I foresee myself experimenting with the different options it provides. I have videos and dyno's posted here: LTH with HFC + CBE = ? There are updated videos and dyno's at the end of the thread with intakes and pulleys installed. Let me know if you would like me to repost them here.
