The AR25 is our most popular resonator because of its versatility. It is a perfect resonator to tone down the noise levels on your car, truck or SUV, and is an ideal choice when configuring a complete TDI exhaust system.
Dimensions are: 2.5" input, 2.5" output, 4" body x 10" length, 14" overall.
An additional resonator can be used end to end or in conjunction with our Magnaflow/Eastern catalytic converter to keep things quite without any flow restriction or snuffing out all delightful TDI rumble. Stainless steel construction built to outlast your vehicle. Added into the system where the muffler was initially installed will drop exhaust noise by about 20 percent.
