Cabin heat, sound, and fumes
Rear-exit routing moves exhaust discharge behind the cabin and can reduce firewall heat and in-cabin sound compared with a front-exit system. Tall windshields and roof systems can change airflow around the vehicle and may increase the possibility of exhaust odor entering the cabin.
Battery-tray and vehicle modifications
The system is designed around an unmodified factory battery-tray area or the Twist Dynamics Optima Yellow-Top battery-tray conversion. Other modifications near the exhaust routing can affect clearance, installation, safety, performance, and warranty coverage.
