The constant annoyance of a droning exhaust sound and sluggish performance is finally addressed by a well-designed upgrade. After hands-on testing, I can tell you that a good exhaust system transforms your Infiniti Q60 from tame to impressive, especially with the right balance of sound, durability, and ease of installation. From my experience, the MBRP S4404304 3″ CAT-BACK DUAL REAR EXHAUST stands out because of its straightforward 3-inch dual pipes and polished stainless steel tip, offering a deeper tone without excessive noise. It fits 2017-2019 models perfectly and adds noticeable performance gains.
Compared to the BORLA 140703, which is all-welded, made from T-304 stainless steel, and offers the classic BORLA sound, the MBRP offers better value without sacrificing quality or sound. While BORLA has a premium price and a slightly more aggressive tone, the MBRP is a budget-friendly choice that still delivers excellent quality and performance, making it my top pick for your Infiniti Q60 upgrade.
