This system is well designed for easy installation in less than 45 minutes once the stock exhaust is removed. Total time was about two hours since my stock exhaust had to be cut at the rear axle with a reciprocating saw to remove. All seams fit perfect and accu-seal clamps are top notch. Quality of exhaust is outstanding and the stainless double-walled tip completes the finish. The performance is noticeable when accelerating and the sound is more aggressive than stock but not too loud. Have seen a 1.5 MPG gain and the engine is running a little cooler.
