Does anyone know whether these will bolt right up? The Y-Pipe goes from 2.5" inlet to a 3.0" outlet. While the mid pipe is 2.5" and 3" in the back. 2006 G35x So far they seem to fit. I'm just concerned that the connection is from 3" down to 2".

So the megans a good fit as well as the m2 08+ for us guys with 0535x?

 

I would go with ISR over any if they make one for your car. Check conceptZ

Megan can be disappointing

 

So I got in contact with aam competition and they make a y pipe specifically for the awd g cars. Its slightly more expensive than the rwd option it is 2.5" in 3.0" out and will fit stock exhuast aswell.
