So I got an 05 G35 coupe 6MT that's been slightly modified already. I want to change the muffler. It has TopSpeed test pipes and DC headers. I thought the rest was factory but after taking it to the muffler shop to have some rattles fixed, I found out it's not factory. It's got a resonator that the muffler guy thought was from a Ford. It's two in, two out. I thought the muffler was factory too, it says Nissan on it. But after searching for some axle-backs, and seeing the factory G35 muffler, it looks like one in, two out. The muffler on mine is two in, two out. So I googled the G37/370z muffler and it looks exactly the same as mine.

I did a lot of researching different exhaust sounds for the G35. I found a few I like but it's hard enough deciphering which videos have test pipes and which don't. Now I have to try and compare muffler sounds from cars that don't even have the same engine.

So right now it's pretty raspy. There's no drone and it's quiet at idle but kind of loud on the throttle and pretty raspy. Honestly it sounds like a 4 cylinder and I hate that. I want to quiet the rasp and make the tone a lot deeper, or at the very least make the tone deeper. So I guess my question is what g37 muffler is going to sound good and deep on a g35, but not too loud? I don't want to do a whole catback unless it's cheap and has the sound I want. So just muffler recommendations.

 

Swap out the resonator with a Vibrant Ultra Quiet Resonator. Its a drone/rasp killer. Still have a nice deep tone but it should sound significantly better. Probably need two side by side (they aren't very big) so should fit where the current 2 in/2 out one is.

 

Great idea, thanks for the recommendation! So having two of them could I expect even better results?
