anyone know if a company makes a muffler for the g35 coupe that doesnt make any noise?, i know the car is quiet already but i want it really quiet...not even the distintive sound that it has.....like stealth quiet...thanx for your time

 

I don't think you are going to find a muffler much quieter than the stock one. You could add additional silencers along the way to it and then change out the tips for something smaller.
