Japan auto inspection sound level compliant exhaust.
This is a premium straight type exhaust which meets the sound level set by the Japan auto inspection system.
The main pipe and silencer are made of a high quality SUS304 stainless with all the TIG welding done by hand. The dolphin tail, which is the signature of J's Racing exhaust, has a 114 mm diameter and presents a very impressive appearance. All the exhausts are hand made one by one by a very experienced craftsman for the superior quality.
The structure is 70 - 70 x 2, which works well both for a better performance from a boost up and for maintaining ample torque at a lower rev range.
Exhaust sound level 89 db/a (estimated)
