Sounds really good in low rpms and can feel the power in the high rpms. I did also do the throttle body spacer.

I had the kit on my 97 Tahoe and I just had to put it on my 04 envoy. I notice the difference as soon as installed it.

Installation was about average, performance gains were nice. My Envoy is a lot funner to drive now.
