Forced induction and OEM exhaust
Soooo, as I am sure many of you have seen the single turbo build I am working on here. If not:
http://www.the370z.com/forced-induct...rbo-build.html Today I had a closer look at the OEM exhaust system, and can't see anybody using this in conjunction with any forced induction system. Since my customer has the F.I exhaust system, and it seem a lot of people on this forum have it as well, I was thinking that I should not even bother with a down pipe that would bolt up to the OEM Y-pipe. How many aftermarket exhaust systems are out there for the 370z that do use an aftermarket exhaust system that would bolt up to the OEM (or aftermarket) Y-pipe? I see that Tanable makes one: http://www.octanemotorsports.com/images/T70150.jpg DC sport: http://www.racingsolution.com/images...nister2Tip.gif and Litespeed: http://www.maperformance.com/product...0z_catback.jpg How popular are these exhaust here? These would bolt up to the OEM Y-pipe so I would have to build a separate down pipe for an exhaust like this. Feedback is greatly appreciated. |
I don't think they are very popular. Most people here have FI, HKS, Invidia, Ark or Greddy
|
... I'd say your pretty safe in ruling these out ...
|
The exhausts listed aren't very popular. What about Motordyne?

Thanks for the feedback so far. It looks like Motordyne uses their own V-band setup, and it would most definitely not bolt up to the OEM Y-pipe.

why would you want to keep the oem y pipe thats the most restrictive part of the exhaust.:icon14:
|
GT haus uses the stock Y pipe. Unfortunately it is over priced.

From what I have seen, many of the high-end exhaust uses the stock Y-pipe design. This could be the reason why most people stay away from them because they go for 3000+++.
|
So it is safe to say that true duals are most commont then?

I use the Motordyne XYZ Y pipe in conjunction with the Tanabe exhaust. I like this combo a lot and the fitment is perfect. PM me if you need to know any details

Just a thought. With the Berk exhaust posted above, I would cut (prependicular to flow) the X section of the pipe right in the middle, flatten a 3" piece of tubing in to an oval and weld it to the X section. that is very easy and I have done it before. Ha, look at that I even have a picutre of it: http://i137.photobucket.com/albums/q...k/IMG_6254.jpg |
another thought, i could purchase the MD exhaust and have it shipped directly to you.
edit: perhaps ship just the mid-pipe to you? |

i ninja-edited my original post. would you need the whole exhaust or just the mid-pipe? |

Remember, I need to build two kits here, one for the car to drive away with and one for me to keep so I can build jigs in order to duplicate the entire kit so that it is a perfect fitting kit every time |

Awesome! thank you! I was planning on going to a custom route... maybe not anymore... lol! |
Why not design an all around kit that will fit the OEM exhaust setup. Then design your own exhaust on top of it? Or give buyers to buy the mid-pipe + short tail from a different source.
I think AAM designs a short tail and a few other companies make the mid pipes. |

I will stick with the F.I down pipe, and will make the one to bolt up to the OEM exhaust...it won't hurt to have around just in case. |

Sasha, I'm curious what your recommendation for the exhaust would be, had you not been given a car w/ a FI exhaust already installed. i'm guessing you're running something custom on your 350. would you be willing to include an exhaust option for those who want a complete turn-key kit?

That is probably one of the cheapest options that I can find. I may even just try that exhaust out and see how it works with the kit. |

Sasha, what don't you like about the OEM exhaust? Is it the muffler design? If so, would these work? They are an axle-back replacement for the stock muffler...

Of course a dual 2.5" would be better, but the OEM mid pipe with the muffler delete pipes should work fine. |
I'm FI and running Exoticspeed exhaust, they make two options one for Turbo and one for NA. I stayed with the NA set up because I went SC and not Turbo. But they do make a turbo application along with HFC's or TP's, Check them out. VERY VERY good stuff. Sound is amazing, Every where I go people are asking me what system I have.
