The aFe MACH Force-Xp Hi-Tuck axle-back exhaust (part 49-48070-1) is a 2.5-inch, mandrel-bent 409 stainless replacement for the factory rear exhaust on the Jeep Wrangler JL. Per the manufacturer, it replaces the stock, low-hanging muffler assembly and gives extra ground clearance when off-roading. It uses the factory front resonator pipe to produce a more aggressive exhaust tone. This -1 version ships with no tip, so the Hi-Tuck tip is not included. The polished (-1P) and black (-1B) tip versions are separate part numbers.
Compared with stock, the manufacturer says this system is lighter and installs higher under the vehicle, which helps when you crawl over rocks or take steep descents. Its 100% MIG hand-welded construction and 2.50-inch 409 stainless tubing are meant to hold up to long-term use. That matters on salted roads, where stock exhaust hangers and clamps often rust. The result is a deeper tone and better ground clearance than stock, backed by a stainless build that will outlast a cheaper mild-steel axle-back. For a JL owner searching for a Hi-Tuck axle-back, a 2.5-inch 409 stainless system with factory hanger mounting is a direct fit for a stock-style setup.
The manufacturer lists fitment for 2018 through 2026 Wrangler JL models with the 2.0L turbo four or the 3.6L Pentastar V6, in both two- and four-door bodies. The system uses all factory mounting locations and OE-style bayonet hangers to hold the pipe steady under vibration and heat. Owners on user forums describe the stock rubber hangers as the hardest part of an axle-back swap, so a hanger-removal tool and a lubricant on the hangers make the job much easier. If you are researching a JL axle-back, an aFe Hi-Tuck with OE-style bayonet hangers is a practical choice for a Wrangler JL 2.0T or 3.6L exhaust upgrade.
No. The manufacturer lists this -1 part as No Tip. The polished tip version is 49-48070-1P, and the black tip version is 49-48070-1B.
The manufacturer lists fitment for 2018 through 2026 JL models with the 2.0L turbo four or 3.6L V6. Details vary across sources, so confirm your model year and engine with the manufacturer before ordering.
Owners on user forums say the factory rubber hangers are the most difficult part of the job. A hanger-removal tool and a lubricant such as WD-40 on the hangers help them slide off.
This is a bolt-on job that uses the factory mounting points, so no cutting or drilling is needed. Owners on user forums report roughly several hours of work with basic tools, one person, and no lift, although the hangers can slow you down. Work only on a vehicle supported by a lift or jack stands. Before you install, remove any burrs from the pipe ends with a round file, as owners of a related aFe kit recommend. Snug the band clamp and position the tailpipe before fully tightening, then check the alignment again. Use a ratchet rather than an impact wrench on the clamps.
