Show original supplier description
The MBRP Installer Series exhaust system is engineered to replace restrictive factory exhaust components, aiming to increase performance and enhance the auditory experience of your 2013-2018 Ford Focus ST with the 2.0L EcoBoost engine. The system includes high-flow mufflers and T-304 stainless steel exhaust tips with a rolled edge for a refined appearance and lasting shine. It is important to note that sound is subjective, and MBRP does not warranty exhaust sound. The "Installer Series" comes with a limited three (3) year warranty, which covers defects in material or workmanship under normal use but excludes pitting, stone chips, surface rust, and penetration rust. The warranty is limited to the original owner and does not cover the cost of removal or replacement, nor damage caused by improper installation, abuse, or misuse.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
