Ok. This is an '08 G35 Sedan, and I know this is the G37 site, but the other site can be slow, so I thought I'd share here, to compare to the coupe.

I removed the entire catback system. Then installed 2.25" pipe to a Magnaflow internal x-crossover resonator, out with 2.25" back to two Magnaflow oval mufflers. The tips are double wall with the internal tapered end but hard to see with the pics; they look better in person than they do there. I have roughly $450 in this system. Would like to do HFC but afraid it's going to be a tad too loud, especially inside... you know how the women can be with that stuff.

sickkkkk, my exact set up HFC w magnaflow
experiencing any drone?

 

I have a slight bit lugging around at 2200 to 2800 rpms. DS mode helps keep it at bay some. I think I have a youtube showing the drone also, where I was keeping the rpms purposely in that drone area so everyone can hear. it's not really as bad as the vid sounds...

that vid was added to the first post.

 

I don't know if I'm just deaf or what, but that sounds extremely similar to stock to me. Not a huge difference. Were you going for HP gains or sound? Did you dyno at all?

 

The look of that setup is 10x better than the one they have going for the Coupe.

 

nice, i had those exhausts on my previous v6 altima, they made the car sound awesome

 

What are the HP gains with this set up if any?
