5 to 6inch tip
not sure where you are from but Hucksdorf diesel has the tip you need.I bought one from them awhile ago and still looks good>>>hucksdorfdiesel.com>>they are on the south west side of milwaukee wis>
i had some work done there!! they do a great job!! i bought a 5" to 6" tip there 4 years ago and it still looks amazing!! im from iowa but i actually helped built the newer hospital right there on that corner!! i cant remember the name of it. but i do agree with blowinsmoke03 they sure do a great job and are very friendly!!
