http://www.scienceofspeed.com/products/exhaust_airflow_products/NSX/ScienceofSpeed/FI_Exhaust/Simply; has anyone bought this? I'd like to see/hear it, and what you think of it. i'm looking for a high flow exhaust with a really deep note from cold start. The GT-Rom 5.1 I currently have flows pretty well [since the cans are blown out], but sounds like crap until it really warms up...
