Good price! Good quality!Can feel a definite power boost. Great sound when you step on it & quiet when you are cruising. Sounds strange when the engine switches from V8 to V4 so I ordered a range active fuel management disable device to keep the engine running on all 8 cylinders.

Installation instructions were spot on. Need to spray pipe ends with lube so they will slide all the way in and twist easier. Quickly installed, sounds and looks great. Noticed HP gain right away, don't know how gas mileage will be effected yet.
