Looking to change out my exhaust tips. I have 500 efi's with E-Tops and the Corsa tips, that have the built mufflers. Im guessing they are either 4 or 4.5" inside, and approx 6" or 6.5" on the outside. I personally like the look of the larger diameter. What I'm looking to do, is a slash cut with internal flapper, and same design... 4/4.5" inside and 6/6.5" outside. Im guessing Id have to get something custom made. Any ideas, suggestions? Has anyone else done this?

had my local metal fab shop make tips for me, have 525's and was shipped from the factory with the corsa mufflers that were 6" on the outside. they were able to weld 4" inside and 6" outside on the flange and match the bolt pattern so zero fiberglass work. then bought the flappers from corsa and put them in myself. pictures are before and after polishing, not a big fan of polished/chrome so was going to stay with the raw stainless look but was really hard to keep clean so i broke down and had them polished...

I also contacted corsa for this project they were quite a bit more expensive, but if you don't have a local metal fab shop may be your only option

I have been doing the bolt on and the weld of these that I get made all SS.

the bolt on of course is simple to do. 4 inch to 5 and 4 inch to 6

Thanks for the input guys, much appreciated. 30outlaw, sweet looking boat and set up btw.
