Tunable exhaust system

A tunable insert assembly for a tunable exhaust system, comprising:

• a baffle insert having a first open end and a second open end, wherein the baffle insert comprises one or more predetermined diameters and lengths, and wherein a plurality of perforated openings are disposed through the baffle insert;
• an orifice plate having a first end, a second end, and an opening, wherein the baffle insert is perpendicularly disposed through the opening;
• and
• wherein the orifice plate is clamped, where the clamping securely holds the orifice plate, thereby avoiding rattling;
• wherein the outer surface of the orifice plate extends along a peripheral outer circumference of the orifice plate, while an inner surface of the orifice plate extends along a circumference of the opening;
• a concentric register ring having a band-shaped solid body circumferentially disposed over an outer peripheral surface of the orifice plate;
• a first portion of the insert extends laterally from the first open end to a perpendicular intersection of the first end of the orifice plate;
• and
• wherein the baffle insert is configured to:
• direct air from the first open end to the second open end;
• and
• produce a range of tunable sound pressure levels and a tunable sound frequency range based on one or more predetermined diameters and lengths.

A tunable exhaust system, comprising:

• an intake tube having a first end and a second end with a first flange;
• an exhaust tube having a third end and a fourth end with a second flange;
• a V-band clamp configured to securely affix the first flange of the intake tube to the second flange of the exhaust tube;
• and
• a tunable insert assembly having a baffle insert, an orifice plate, and a concentric register ring, wherein:
• the tunable baffle insert has a first open end and a second open end, and a plurality of perforated openings disposed through the baffle insert;
• wherein an outer surface of an orifice plate extends along a peripheral outer circumference of the orifice plate, while an inner surface of the orifice plate extends along a circumference of the opening;
• a first portion of the insert extends laterally from the first open end to a perpendicular intersection of the first end of the orifice plate;
• and
• wherein the tunable insert assembly is configured to:
• direct air from the intake tube to the exhaust tube;
• and
• produce a range of tunable sound pressure levels based on one or more predetermined diameters and lengths.
