Greddy E-Manage or 3sx Downpipe

I have the oppurtunity to get the E-manage for about the same price as the downpipe. So I was going to get the Emanage and then I won't havta get the SAFCII in the future. So my question is what are the pros and cons of the E-manage as opposed to the SAFCII? Where would my money be better spent, the downpipe or the Emanage? By the way the emanage also comes with the ignition harness that normally costs an extra $40. Keep in my that I'm just a poor college student so i'm trying to keep all of my mod costs as low as possible but still do things the smart way.

Hmm, I actually know nothing about the E-manage...hopefully someone else will be able to jump in with more specifics...

But if you have a great deal on it, and it will save you $$ in the future...I'd say go for it, especially if you have larger turbos or injectors or are planning to get some in the future.
