aFe POWER's new Mach Force-XP series cat-back exhaust system for your Toyota 4Runner with the V6-4.0L engine will get you there with speed and style. Designed from 2-1/2" & 3" mandrel-bent, 304 stainless steel, this exhaust system offers greater flow to deliver more torque and horsepower than the factory exhaust. This 4-piece designed cat-back system utilizes a less-restricting, high-flow, muffler to improve your 4Runner's performance while maintaining a deep, smooth tone. 100% hand MIG-welded by certified craftsmen for proven quality and durability, the Mach Force-XP exhaust system includes a 4" x 12" polished resonated exhaust clamp-on tip to give your 4Runner a clean, finished look.

Features:

  • Increases horsepower and torque
  • Improves performance
  • Lowers exhaust gas temperature
  • Flow bench and dyno tested
  • Welded hangers with swaged ends
  • Slotted and swedged ends
  • Premium quality band clamps
  • Backed by a 2-year limited warranty
  • Proudly made in the USA

A performance exhaust system is one of the most common ways of improving a vehicle's operation. The theory is simple; just reduce restriction to increase exhaust flow and you gain power. But all exhaust systems are not created equal; in reality there's more to it than just selling some sewer pipe sized tubes.

aFe tests its systems on the flow bench and the dynamometer to determine the right pipe size and muffler construction. Then they mandrel bend the pipes to ensure they maintain their shape and size throughout the entire length, to provide smooth, unrestricted airflow. Tubes that are not mandrel bent can lose up to 20% of their diameter in sharp bends. Some systems also include a straight muffler delete pipe if a more aggressive sound and maximum flow is desired. A typical aFe system will increase exhaust flow by up to 29% and lower EGT (Exhaust Gas Temperature) by up to 100º, with a corresponding improvement in power and performance.

But performance is only part of the equation. A quality exhaust system should be easy to install and made to last. The muffler and all pipes of the Mach Force XP system are constructed from durable 409 stainless steel. To ensure a tight seal, slotted and swedged ends are used whenever possible. When used with the supplied premium quality band clamps, the tightest, leak-free seal is the result. Every hanger is thoroughly welded

Perfect fit for my fit
Size: 2" x 10" x 11"
Bought this for my Honda fit sport. Perfect fit for my fit. We shall see how it works out in the long run. I'm guessing every six months I'll wash it out, give it a light piling with the refresher kit I bought. The car doesn't get driven a lot during the year, so, doing it this way should be more than fine.

Premium, Reusable Cabin Filter – Worth It Long-Term
Size: 2" x 10" x 11"
I've been using the K&N Lifetime Washable Cabin Air Filter in my vehicle for several months, and here's my experience: Pros: Washable & Reusable: Eliminates the need for frequent replacements, saving money over time. Improved Airflow: Noticed a slight increase in airflow through the vents, enhancing cabin comfort. Odor Control: Effectively reduces musty smells, providing a fresher cabin environment. Cons: Initial Cost: Priced higher than disposable filters, but the long-term savings offset this. Cleaning Required: Needs periodic cleaning to maintain performance, which might be inconvenient for some users.

My brother put me onto these filters. Super easy to install. Also bought engine filter. One time expense. A bit pricey but cost covered if you were still buying paper ones in about 3 changes of paper ones. Will definitely pay for themselves. Highly recommend
