This unit is required to achieve sound level 4 & 5 with our exhaust system.
We can NOT guarantee "NO CEL" with this unit because every car has different emission spec depending on the country.
*Since every exhaust is built to order specifically to customer's request, all of our handcraft systems take 14-20 days to build after the purchase. All of our exhaust products are made in house. Made in Japan.
