Low back-pressure Moroso Spiral Flow race mufflers cut noise by 5 to 7 decibels on their own. In total, this system can bring the overall decibels down from the 112-115 level to 100 decibels or less. Check your track’s decibel limits and the location of the meters around the track. All “slip-fit” for easy assembly; includes four straight sections, two mufflers, two down-turned tips and two heavy duty hangers. Welding is required for installation and requires 3” header collectors. The final installed length is 79” to the exit point in front of the rear wheels. This kit is also available with an “H” pipe which is supplied as unassembled “fish mouthed” sections to be final slip-fitted and welded together. The advantage to running an “H” pipe is added horsepower throughout the entire RPM range through equalization of the pressure waves. Fully adjustable to accommodate your headers, holes must be made in the intermediate pipes at the proper point, and then the ‘H” must be cut-to-fit and welded into position. Additional flange kit will be required if bolt-on type header collectors are used.
