The MagnaFlow BRExhaust 106-0148 is a direct-fit replacement exhaust for the 2004-2008 Acura TSX 2.4L. The kit is a replacement for the stock exhaust system while providing a reliable and high-quality alternative to the OEM exhaust. Its pipes are precision mandrel bent, which the manufacturer says facilitates superior exhaust flow compared to the crush-bent pipes commonly used in competing aftermarket replacement exhaust systems. The main reason to pay for it over a budget replacement is factory-style fit and durability, not horsepower. Owners on user forums generally report that a cat-back alone adds little measurable power on a mildly modified TSX.
The system is built from aluminized steel and carries a two-year warranty. It is engineered for OEM 18030-SEC-A00 exhaust replacement, and the manufacturer also lists 18035-SEC-A00. Searchers looking for a 2004-2008 TSX 2.4L cat-back replacement, bolt-on OE exhaust, or 106-0148 direct-fit muffler kit will find this matches those needs. For the install, no bending or welding is required, and the kit includes its gaskets and clamps. Owners on user forums advise supporting the car at both ends before removing the last hangers, using a breaker bar on the catalytic converter flange bolts, and replacing the exhaust seal ring.
The manufacturer lists the kit for the 2004-2008 Acura TSX with the 2.4L engine and engineers it against the OE part numbers above. Confirm your model's exhaust layout with the manufacturer before ordering, since factory configurations can vary.
Owners on user forums generally report that a cat-back exhaust gives little power gain on this car. Buy this kit for OE-style fit, aluminized construction, and sound, not for a large horsepower increase.
This is a bolt-on job, but it is not quick. The manufacturer describes a multi-piece, adjustable design that can be worked around axles, crossbars, and brackets. Owners on user forums recommend ramps or jack stands at both ends, a breaker bar for the bolts near the catalytic converter, and penetrating lubricant or petroleum jelly to free the rubber hangers. Support the exhaust before removing the final bolts, and expect some fine adjustment of the hangers to get the muffler height right.
