Hi,so this is the first time i have had a car like this and dont really know much about the exhaust that i currently have. So when i bought my 350z it came with a duel stainless steel exhaust with stainless cats and when he started her up the noise off it was unbeleivable and was just the perfect tone and volume (really loud) so when it picks up past 2,000 rev it makes that nice loud un describable noise and then has a small thunder noise that you can feel.
So that noise which i described as thunder was always there when i started her up and stayed with me wile she was warming up but as of today i have noticed that this noise has gone and seems way to quit when starting up. Why is this? I do notice that when i had this noise it sat at 1 and a half rev and now when i start her up shes only 500.
Sorry for the long post but i really want my noise back when its sitting still at traffic lights
