Upgrading the Exhaust System on Jeep Cherokee XJ for Performance morsunled.webflow.io

One of the primary motivations for an exhaust upgrade is auditory. The 4.0L inline-six has a unique voice—it is not a V8, and trying to make it sound like one will only lead to disappointment.

Flowmaster's FlowFX system, for example, offers a "moderate deep powerful sound" with mandrel-bent tubing that tucks up high to avoid trail damage . The key is finding a system that is "throaty and authoritative yet civil"—loud enough to announce your presence on the trail but quiet enough for daily driving without droning .
