Xforce VAREX Cat-Back Exhaust System

This system integrates Xforce's patented VAREX Valved technology, enabling drivers to precisely control their exhaust's sound output and tone using an included remote control. For those seeking further customization, an optional resonator-delete pipe is provided to fine-tune the sound level and character. Constructed from durable 304 stainless steel, the system boasts 3-inch mandrel-bent pipework designed for optimal exhaust flow, reducing back-pressure for improved performance. It culminates in dual 4-inch polished stainless steel tips, adding a visually striking element to the rear of the vehicle. The VAREX muffler itself features a straight-through design, contributing to maximum power and sound delivery when open. Installation of this cat-back system is described as relatively straightforward, with one user noting a perfect fit on a 2019 GTI Autobahn Mk7.5. It involves unbolting existing hangers, transferring them to the new exhaust, and reattaching. While a lift is helpful, it can be managed with basic tools. The user suggests purchasing a new 65mm exhaust band clamp and recommends an exhaust hanger removal tool for ease of installation. This system is specifically designed for the Golf GTI MK7 to MK8. The product page and search results confirm fitment for various GTI models within this generation range, including MK7, MK7.5, and MK8. Compatibility with future modifications, such as downpipes and stage 2 tunes, is also mentioned, with the VAREX system offering the flexibility to manage sound levels.
