Hi there,

Deciding between 3.5" or 4.0" exhaust tips (od) on a stock g37xs sedan in black.

Let me know!

 

If you keep your G closer to stock then the smaller tips will look more in line, the more aggressive you go as far as lowering and wheel setup the more I'd lean toward the 4s.

 

thanks blnewt! I am planning to have the tips welded on my tanabes (they came without tips from a seller)

do you know the od size of our stock tips? will 3.5" tips be smaller or larger than the current oem tips? that would really help me decide!

 

I posted a reply to one of your posts in another thread, in case you don't see it there, here it is: https://www.myg37.com/forums/g37-sed...ml#post4087324

 

4.0 looks good!

 

3.5" is way too small. 4.0" for sure.

 

Oval or round?
Slanted or straight?
Beveled or rolled?
Single wall or double?
Resonated or not?

Take your time, OP. Lots of considerations.
