Hey guys,

Q1: will the 370z or 350z isr y pipe fit the 07 g35x sedan awd? Which one?

Q2: will the 370z or 350z isr resonated test pipes fit the 07 g35x sedan awd? Which one?

Q3: will the 370z or 350z isr single exit exhaust fit the 07 g35x sedan awd? Which one?

thanks a lot I’m a noob in cars lol!!!

 

A1: No, the X has a specific Y-Pipe in order to clear the transfer case.

A2: Yes, ONLY if they are listed as compatible with your engine (VQ35DE or VQ35HR), I'm not sure if there is compatibility between the 37VHR and 35HR.

A3: No, the design of the exhaust after the Cats is completely different between the coupe and sedan. IF there is any compatibility it would be the Y-Pipe and that would only be applicable to RWD sedans due to the X having the transfer case.


Edit: This knowledge was through numerous searches while planning out exhaust replacement for my 2008 G35x and as such may be incorrect. Others may chime in with correct info at which point I will digress in order to insert my foot in my mouth.

 

yo will it fit on the 2006 g35x

 

That's still a no to questions 1 and 3, and a questionable for the test pipes.

Sedan and coupe exhaust systems are very different, regardless of generation. I'm not sure if test pipes for a DE on a coupe will fit into a sedan or not.

 

I don't think DE cats/pipes fit the HR, different flange.

DE to DE I think they were the same regardless of whether or not it was an X.

 

I too have an 08 g35x and have been spending lots of time looking to upgrade my exhaust and have met very limited options. What did you find to be available for your G35x

Q1: will the 370z or 350z isr y pipe fit the 07 g35x sedan awd? Which one?
-Either one can be made to fit. the 370z is the most common to work on the V36, coupe and sedan with extensions. to get a better fit, some cut and rewelding is needed. but can be installed with 16" to 24" extension depending how far you want the muffler to end relative to your bumper

Q2: will the 370z or 350z isr resonated test pipes fit the 07 g35x sedan awd? Which one?
- 370z/G37 have VHR engines and 07-08 g35 sedan and 07-08 350z have HR engine. both share the same flange type. all other old years 350z and g35 have DE engines and have different flanges.

Q3: will the 370z or 350z isr single exit exhaust fit the 07 g35x sedan awd? Which one?
- the 370z isr y pipe is 2.75" primary diameter and fits awd, despite websites saying it won't. I have verified. the 350z is 2.5" tubing
