I have the 3.5 and as long as you don't use their stupid plate (which smacked the plastic trim on the firewall even with my SU motor mount), it's fine. big jump in power... it does rub on the ducting attached to the hood, but that's what happens when you start modding cars. I think the 3.25 would clear, but I can't say for sure. All the same, I just bought the Cobb front mount. I think it will work better for what I do. I've loved the ETS though! If you can get one for a good price, DO IT!
I had the same issue with the firewall when I first installed mine. I trimmed the shroud a lil and haven't had the issue since. AND yes the shroud still makes perfect contact with the hood duct. I love this tmic but I just recieved my tax return and want the "show" quality of a FMIC haha. I'm selling her for $350 + shipping. 3.5" ETS TMIC fully polished. I'll post her fri or sat.
as long as everything looks good I call first dibs on madtig's tmic
already pm'd him yesterday (evil)(crazy)
that's what i wanted to know about the 3.5". I ahve stock mounts in mine and would hate it to get damaged if i banged hard through the gears
