// JEEP PERFORMANCE & EXHAUST — QUESTIONS ANSWERED

How much horsepower does a cold air intake add to a Jeep?
A quality cold air intake adds 5–15 HP on the 3.6L Pentastar, with better throttle response and a more aggressive intake growl. Pair it with a tuner for combined gains of 20–30 HP.
Will a performance tuner help with bigger tires on my Jeep?
Yes — a tuner recalibrates the speedometer for larger tires and can adjust shift points and throttle mapping to recover the acceleration lost to heavier 35s or 37s. It is the most recommended mod after re-gearing.
Cat-back vs axle-back exhaust — what is the difference?
An axle-back replaces only the muffler section (sound upgrade). A cat-back replaces everything behind the catalytic converter for maximum flow — slightly more power and a deeper tone, at a higher price.
