Y-pipe + HFC's with stock exhaust
 

Right now the only performance mod i have is a pop charger. I was thinking about an aftermarket Y-pipe along with Kinetix HFC's for some extra sound and maybe a few HP withoutout droping a grand on an exhaust. The only thing i am worried about is the loss of low end torque with the Y-pipe. But I've also read that the stock Y-pipe is one of the most restrictive parts of the exhaust and low end torque loss is not a problem with this setup. Can i get some real answers from some experts or dynos. All feedback is appreciated. Along with other combos you think would be better.

I want to know this also

The deafening sound of silence on this post makes me think no one knows the answer.

I found this post doing a search for an answer to this very question. When you homos throw out the "use the search button" jab just remember this post... :11:

Don't waste your time or money. Neither of those mods have been proven to add a noticeable increase in power. I suggest spending the money on a MD 5/16" spacer and then getting an ECU reflash of some type. Both those mods will add about 4X as much power as the HFCs and y-pipe. BTW, there isn't a SINGLE dyno of a before/after y-pipe install on this site or on my350z.com.
