Hi, I think this is the right muffler to put on a 94 bonneville 3800 series 1. Could some one tell me if this is the right one. Thank you.

80 series Flowmaster muffler part #42583. It has a 2 1/2"ID inlet and outlet on one end and a 2 1/2" outlet on the other

sounds right! I got the same set up!

Yep, thats the muffler on my car....42583

timeout hold up wait *blows whistle*

alright is it an SE or an SSE? everyone forgets the SE only has 2.25 inch piping as compared to the SSE/SSEi which have 2.5....it will still work, just whoever installs it will have to use a reducer of some kind, in other words mo money...

I believe the 80 series only comes in 3 inch and 2.5 inch, so I don't think you really have a choice.

I have an 80 series on mine, have a 2.25 to 2.5 reducer too. sounds nice as **** though.

I have the 2.5" 80 series on my SE. It works fine but has a pretty strong interior resonance.
