The Hartge exhaust is quieter than the RPi GTM because the Hartge design is an axleback system. The Turner Motorsports design follows the Hartge design and is also an axleback system. The RPi GTM was specifically designed to maximize airflow and power generation from the downpipes back. Due to the fack that the GTM has no resonators, it will have drone, but a lot of people like it. I like it because it adds that missing heart and soul feel that the S63tu engine lacks with resonators. Plus the drone is absolutely nothing as bad as the S85 V10 drone.
