I had a NISMO dual system installed yesterday along with NISMO headers. The power is great but I hate how loud it is. I'm scaring old people at stop lights and one lady flipped me off. An aggressive rumble is nice but this is rediculous. Does anybody know about these systems and what could be done about the noise? I hate to start modifying already but I have to do something.:dunno:

Holy crap that is freaking loud how about some highflows and some resos in the b-pipes might help a bit. But I gotta admit that was freaking sweet.

It does have a bad drone. I'll post a clip of the inside cab noise later today. It lloks like I'm going to try resonators first to take the edge off.

I just had the nismo exhaust installed yesterday and mine doesn't sound that loud. I do have the 2 degree advance and nismo intake, but I have stock headers. Mine has a lower rumble, like my cobra from a few years back. I love the duel sound. I would buy it again in a second!

wow that is nuts that sounds like my exhaust with it wide open when i take off the caps to my cutouts

good luck on trying to make it more quiet throw like a 50 series big block muffler on it and it should really help if the resonators dont

Wow, I had no idea, sorry it's so loud and I may be keeping the Zoomers for sure because I just could not deal with that outside the racetrack.
