I used this tip to finish installing my Dynomax VT muffler on my Ford E150 4.6 V8. I just thought it was the right size, but once installed I found it larger. The guys at the muffler shop did something to make it fit. You should have taken the part where you tighten the screws. instead they cooked it well. now it looks amazing! Build quality is excellent. I also like how it complements the muffler sound. definitely worth a try. I am happy with mine :)
