As far as any modification, I didn't do the install myself, but my mechanic didn't mention any modifications he has done, only thing was the pre cat sensor which was welded to oem manifold. So, I had to buy new sensors. Also, you will need either a 20 guage wires to extend the pre cat sensor wires or an extension link, as motordyne will not provide them.

Just went and checked on FI's site and it looks like the mod is for 12+ models as something changed with the coolant crossover pipe that doesn't allow the driver's side header to bolt up.

When I did headers the first time on my Cobra I had to do the same thing. Wasn't a fan of it and would rather run extenders if they exist. If not, I might just make some myself.

Thank you for the heads up on the wiring i'll make sure to have something ready before I start if I go with the Motordynes.

I'm in love with the FI LTHs. Sounds great and fantastic power combined with my exhaust. They do have some drone at low RPMs. No problem, just keep it at the redline!

testpipe vs LTH, are equally the same?

Motordyne told me that I can find extension at radio shack. Being at the other side of earth, didn't have that option so went ahead and bought wires to extend. Unlike Md, fast intention offers a hardware kit to solve this issue, so you will run into the same issue with either headers, because they re-located the sensor position, maybe for better af reading, as my car didn't through any check engine signs after installation.
