These compact auxilliary silencers can be easily added to existing systems when noise regulations require a reduction in decibel output. Ideal for acheiving noise level requirements for track day, test or race days they have an integral decibel insert that allows them reduce exhaust noise by siginificantly more than there size would suggest.
They have a case length of 8" and a case diameter of 4", we offer them in a range of inlet sizes from 2" to 3" i.d. in 1/4" increments.
