Installed a aftermarket y-pipe with stock exhaust....

abdulisraddd · 05-26-2016, 09:16 AM

So yesterday I installed an aftermarket y-pipe I believe it's a 2.5 to a 3 inch , to my stock exhaust . The only other thing I have on the exhaust are berk resonated test pipes . Has anyone ran this set up? Tried doing a lot of searching and couldn't find much. Now my car s test pipe hissing is 10x louder lol and I do feel a little lag. And on accelerating I get test pipe hiss also. I'll try to get a clip later today . Just wondering if it should sound like this from people that have ran aftermarket y-pipe and test pipes on stock cbe
-thanks

As soon as you take out the cats, you'll get hiss.

Do you have any resonators in the system?

I still have my resonators on! Also the hiss was only on deceleration before the new y-pipe now the hiss is way louder and hisses as soon as I let off the gas. The most noticeable difference is the cabin noise is very loud before it wasn't that loud until after 3.5k rpm. Exhaust leak maybe ?

You say the Y-pipe is 2.5" to 3"??

Stock exhaust is not a 3"

I have an aftermarket y-pipe (2.5 to 3") with Nismo exhaust and I don't have the crazy hiss sound op is getting. Should try checking for leaks at the connections and retighten everything again.

That cant be good for flow though since it necks right back down after the y-pipe right??

No ill effects I could tell. The car actually pulls much stronger in the mid range so the increase in power is apparent going from stock y-pipe to a larger diameter Y-pipe. I should mention that I started with Art pipe and Nismo exhaust (Nismo S-tune mid pipe) before swapping out the stock nismo Y to the XYZ y-pipe.

Took it to precision z and found out this was a 350z pipe

I've got an extra aam y pipe that bought off another member here that's sitting around. It's up for sale. You can do a quick search for aam y-pipe to learn more about it.
