It is bolt on. One of the best sounds, but one of the worst for performance. I am losing horsepower on mine. I have to get rid of it and get something more free flowing.

oh man i hate to hear that. i had orginally thought of the edlebrock system, but its made for the v8's. would this one bolt up directly, or would some fabricatoin be in store.

Should be a direct slip fit. but I hate to say, I cut mine off due to horrible tin can sound and performance was too restrictive for me. For your 3800II, I would not recommend it. But its your choice. You can always return it unopened. I used a custom exhuast setup, but If I were to use a ready made, i would prolly go with MagnaFlow or Dynomax. I am not impressed with Edelbrock's muffler design. I am running a glasspack in my setup. But any straight through- non chambered design will lower restriction and produce more power. Anone with a LS1 or newer should not even think of using one. -Tim
