More exhaust flow will give your Jimny more power and torque.
The AVO 2" front pipe kit for the JB74 3 door Jimny is constructed from high-grade 304 1.5mm stainless steel which ensures longevity and aids with noise absorption. Your factory OEM front pipe also uses a fairly restrictive front catalytic converter.
AVO have also manufactured a OEM style flex setup as it is required to fit with the factory OEM cat back exhaust.
Without the donut gasket and OEM spring loaded bolts, then your headers and any welds forward of the flex are prone to cracking. The flanges are stainless steel and are 10mm thick, therefore will not warp under the harshest of conditions. The front flange on the front pipe also has the taper in the flange so that it correctly fits to the factory Header.
Will get more more benefits if completed in conjunction with the Tune.
Note: This will not fit the new 5 door Jimny as it is too short.
