The install instructions are poor at best. Many more steps required than listed in guide.

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.
