Dinan's FMIC is actually a Spearco unit with custom shrouding...nothing wrong with it, but the ETS 5" is a lot easier to install and the connector hardware replaces the more restrictive stock "ribbed" stuff. I went with the ETS 5" and have never looked back. Also, unless you plan on running 600+ HP tune level, a 7" FMIC is overkill - and it requires trimming, no matter which brand you buy. The key is the core design - bar and plate > tube and fin every time.
