Merge Collector Outlet Options
For drag racing and similar applications where a tailpipe is not required, megaphones fitted with reverse cones are invariably the best option. They produce maximum horsepower and maintain the highest and smoothest torque curve. Megaphones also offer the highest potential power past the peak without compromising the lower end of the power band on well-developed engine combinations with optimally short-header tube lengths and a well-chosen collector outlet diameter.
For applications which require tailpipes, a NASCAR-style transition (long or short) and ring is normally recommended. If you are unsure which style is best for you, please call to discuss your specific application.
