I have a Murnan Modified RB C6 with the 9901 pipe and a 98mm RB header. It is a very smooth package with a ton of bottom end as well as a screaming top end. Motor consistently runs in the 220's on a 90+ degree day, and depending on the track size I can get 11-13 minutes (in a Mugen Truggy) on a fuel run.
