Pick Premium Exhaust Donuts for Smooth Engine Performance
Buying a new exhaust system can be one of the most exciting, and most cost-effective upgrades any auto enthusiast can make to their vehicle. But beyond remotely-controllable mufflers, masterfully crafted headers and flashy endtips, there are two far-less conspicuous exhaust components that need to be considered: bent tube sections and donuts.
Ask any exhaust system designer and they’ll tell you: the key to getting the best performance from an exhaust system isn’t in resorting to larger diameter tubes: it’s in maximising airflow. Every section of tubing, and every joint between those sections has to be optimised in order for exhaust gases to move as quickly and smoothly as possible. That’s why our tips for ensuring the best possible gas flow are centred on donuts and mandrel bent tubing.
