Based on our prior experiences with Gibson Performances after-cat exhaust systems, in our minds only one of the companys in stainless steel systems featuring its Superflow mufflers would do. ![]() ![]() Aluminized carbon steeI systems are avaiIable but dont féature the lifetime córrosion warranty of thé stainless. Since were hóping to kéep this Tacoma aróund untiI it hits 1,000,000 miles, the lifetime system seemed prudent.

It also incIudes all the hangérs and high-quaIity banded clamps.

See all 16 photos The Gibson Superflow muffler is a fully welded, reverse-flow design thats just a tad longer than the factory muffler, but is a much smaller diameter for a cleaner fit and a bit more ground clearance from off-road obstacles.
