APR's premium line of Helmholtz Resonators are now available! Perfect for the do-it-yourself enthusiast fabricating a custom exhaust system, these resonators target and cancel out specific frequencies that create drone. Internally the system is open with an small offshoot path leading to the main chamber designed to bounce soundwaves back into the exhaust flow path to eliminate unwanted frequencies. The main exhaust path is a straight through 76mm (3") pipe with offset inlet and outlet. There are no harsh twists, turns, or baffles to slow exhaust flow. You'll get full uninterrupted flow for maximum power. The whole system is made from T304 stainless steel and features strong and attractive TIG-welding throughout. The system is stamped with an APR logo and rolled with two sets of double ridges for additional structural strength and killer looks. To top it off, each system is fully brushed clean providing an attractive premium finish.
