aFe Power Mach Force-ST 1.25 IN 304 Stainless Steel Exhaust Tuning Insert
$73.50

The ST Sound-Core is a patent pending technology from aFe, compatible with MACH-Force ST and Takeda ST exhaust systems . With this technology, you can easily modify the sound and tone of your exhaust system. By placing the ST Sound-Core in between the two stepped V-band flanges in the exhaust system, you can control the amount of flow that is bypassing the muffler, and change the overall tone of the exhaust with the unique reflection-chamber design. With a small diameter ST Core, you can provide a mellow tone on the street, and remove the ST sound core for wide open full volume. The ST Sound core provides the benefits of an active exhaust system without the need for an exhaust valve.

Installation:
ST-Sound Core's machined step design provides a hassle free, bolt-on installation. Simply remove a V-band clamp, and exchange or remove ST Sound-Cores to radically change the tone of your exhaust system.

Premium Components:
Constructed from 304 stainless steel, ST Sound-Core is made with strength and durability in mind, and is finished off with a laser etched advanced flow engineering logo for a unique style.

TIG-Welded:
100% TIG-Welded for race-proven strength and durability.

Emissions Disclaimer:
This product does not require a CARB EO#.

Features:
  • Controls overall sound level by regulating the flow bypassing the muffler
