Okay so I ordered a stillin exhaust for my G 37 sedan I just realized the box that came says for G35 I went to the stillin site and they have two separate part numbers one for the G37 and one for the G35 dual exhaust but are they the same product? I'm supposed to have a shop install it tomorrow so does anybody know? Thanks

 

You should not be having any problems installing. Enjoy

 

I believe there are 3 versions of the Stillen exhaust.
Gen 1 = 03-06 G35
Gen 2 = 07-08 HR G35
Gen 3 = 09+ HR G37

I recall them saying that there is a difference in loudness between the gen's. I have the Gen 2 for my 08' G35 Sedan. You might want to call them and double check though.

 

I believe they sent me part number 504375 witch is the g35 model so there is no diff in the exhaust? No diff in power ect? I'll call at 10 am mine time 7 am stillin time and find out tell the shop to hold off on the exhaust and just install the sways first till I get a answer Thanks everyone

 

There is no difference between 07-08 g35 sedans and 09+ G37 sedan exhausts. Exhaust piping are the exact same

 

So you're saying that the Stillen exhaust for the G 35 sedan is the exact same exhaust for the G 37 sedan Or do you not know i......there are two separate part numbers for both cars

 

i would think the dimensions/layout etc would be identical since the cars body/frame are identical, as far as i know.

however, the engines are not identical, so i could see something small being different. that would probably be in the cats, though, not the cat back exhaust (just piping)

 

Piping/fitment wise they are identical... Now if there are 2 versions of the exhaust as the above poster says there may be slight differences however those differences won't affect the fitment...

Fitment wise, I believe it's exactly the same. As I had stated earlier, I think the only difference between Gen2 and Gen3 was the loudness. I'm assuming you already have it installed though. Let's see pics sir!

 

Yes I called stillin and they told me it's the same exhaust so I deff had it installed, I'm very happy with everything sound and performance
