Why We Choose HJS Catalytic Converters:
HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.

Sound is crisp and noticeable. Great sound for the price.
I installed the Maxflo mufflers after admiring them for a week. Nice piece of kit, especially for the price! Installation of the mufflers was easy, the most challenging part was getting the rear bumper off so budget a few hours time if doing the job at home. The sound is great, not obnoxious at idle, the neighbors won't hate you. Comes alive around 3500rpm. Love the burble and burping when coming off throttle. Another A+ for Fabspeed! Communication and shipping were top notch.
