So; I love my car. I even love how loud it is.
However; when I start it in the morning - it wakes everyone in the house up. I've even tried "Flinstone-ing" it out of the garage and starting it outside
It has a great exhaust setup; and on the road it sounds like an F1 (which I love). It's a Supersprint setup with race cats and Jed's unicorn headers. I'd like to see what I can do to quiet it down at idle without hurting performance.
Anyone have any experience with this? I'm going to code the cold start high idle out - that's on the list.
Does it have an aftermarket X pipe? Resonators? Stock X pipe (actually an "h" pipe) and stock resonators will usually keep noise at a reasonable level at lower rpms.
