I understand basic exhaust mods and I found this group buy
at my350z (10 people $250 shipped or 15 people $225 shipped).
It is for Gruppe-S Y-Pipe - 03+ 350Z/G35 Coupe
76mm Outlet, SS304 Piping, Mandrel Bent, TIG welded.

I am not sure if this will fit the FX35. Looking at the pics of under our FX and looking at the Gruppe-s y pipe it looks too short to hook up in the front. Am I nuts or am I just not looking at it the right way?

Under of FX35



This was on FA and had some info but I am still confused. Something about a g35 extension piece. But it does not say if it will fit up to the front with no issues.

That's the same y-pipe I bought. It won't fit on the AWD FX's. I don't know about the RWD models.

Yea, I was wondering the same thing - what exactly would the expected result or benefit be of installing the Y-pipe but nothing else?

I have their cat-back, too. Again, sitting in my garage collecting dust.

The Y-pipe's outlet is 3", so you'd need at bolt up a reducer from 3" to 2.5" if you go with one of the 350Z exhausts. Or you could stil with a full 3" exhaust.

The cat-back I got with it is a full 3" system.

In all honesty, I can't say that the 3" is the way to go for the 35's. I think the piping is too big for a 3.5L N/A engine. It will shift the power band further up.

The y-pipe, if coupled with a proper reducer, would help make power without sacrificing lower end torque. If you bolt on the pipe to the stock exhaust, it wouldn't be a good idea because there wouldn't be a smooth transition. If you wanted to keep the stock exhaust, you could purchase a reducer and have a shop cut ans weld it into place. Shouldn't be more than $75 for time and labor.

Man, I wish I had my own TiG welder. I'd never get out of the garage.

The Nismo is a 3" system.

I don't have any aftermarket exhaust on my car right now. I'm looking to see if there are any shops in the Chicagoland area that can do mandrel bends. If I find one, I'll have them do a custom y-pipe and muffler setup, using 3" SS piping, a middle 26" resonator/glass pack and a 24" rear straight through muffler leading to only 1 exhaust pipe exiting on the passenger side of the car. And I'll finish it off with a big 5" fart can tip. j/k.

If you absolutly must spend $$ (foolishly) on a Single exhaust system :( At least Start out with a more freer Flowing design, softer curves and less sharp bends. :roll: Enjoy the View
< Now That's a Nice Y-pipe! Don't Stop there, complete the rest of the system. Have it done by your local CUSTOM exhaust specialist for greater savings. http://www.infinitifx.org/phpBB2/viewtopic.php?t=2400
