here is a pic of a 3.5" tip for scale: imgur.com/Webb6Zs.png
Oh geez, I ended up just going with new dual tips for now. I just got my 4" black tips in today, I think they'll fit barely, we'll see though.
I went with dual 3.5" tips that just cleared. I also dremeled the rear m sport diffuser using the template from the remus website for their quad exhaust.
What attachment did you use on the dremmel?
It was similar to the one in the picture, third from the left. https://images.homedepot-static.com/...86-64_1000.jpg
