Agency Power makes a pretty good EL header as well.

This statement is utter bull**** and perpetuates third hand rumors.

My understanding is that AP is a wholly owned subsidiary of Vivid Racing; they are a completely separate company that happens to be owned by Vivid Racing.

I have been buying parts from Agency Power for years with only a single, minor, problem., which was taken care immediately by Matt Jobin of Agency Power.

If Matt says the part is in stock, it is.
If Matt says it's a 2week back order, that's the longest it will take. Another huge supplier in the Subaru aftermarket performance world will string you along with "two weeks" that always turns into two months.

I've never had an Agency Power part fail like I have with two other supplier of performance parts.

I have the tomei UEL headers on my car and I like it alot. It comes with heat wrap and an uppipe as well. What's great about tomei headers is that with its thick pipes, and "lost wax" technology, it isn't prone to cracking as other headers might, so it's more durable over the longer term. I don't have a clear pic of the equal length headers but it's on tomei's website. Here's a pic of the UEL one. Just remember that if u get equal length headers, u will lose the boxer sound.

How is the fitment? Any exhaust leaks from the 3 bolt flange on the uppipe?

The Tomei, Maddad and GT-Spec all look identical.

Ive researched and come to the opposite conclusions. They definitely look the same and read a few reports that the 3 bolt flange is prone to leaking.

How long have you had your Tomei's? Any fitment or leaking issues?

I've had mine for around 6-8 months now (unequal length). No leaking issues at all.

And as far as I know, the fitment is good. I haven't had Kevin (AutoHQ, installed over there) say anything bad about them. But on the other hand, his shop sells them so he may or may not be biased about them.
