Got my FP manifold installed today and figured i'd do a bit of a first impression write up:
The install was just like any other exhaust manifold. You do however need 2 shorter manifold to turbo bolts, and two normal length. Ziggy at RTM carries the shorter bolts.
I did have my manifold ceramic coated by Sheela at WC Customs Powder and Ceramic Coating. I did this after hearing numerous people say how hot this manifold runs, especially without a heat shield.
Now the first impression:
I have to honestly say the car felt a little slower than before, with a 2G ported manifold. The low end seemed to lag a little bit, i fixed this with a bit of tuning through ECMLink and the car felt great once again. The exhaust note at idle was pretty much the same as before, but the exhaust note in the higher RPM 4500-7000, was completley different. It doesn't sound like any Talon i've heard before, it is an incredible sound! As for the heat, i did a number of pulls, checking under hood after each pull. I was able to hold my hand about an inch or two away from the manifold with no problems. The radiant heat is very little. I'd recommend to anyone to get their manifold ceramic coated.
I'd gather an ECMLink estimated 10hp gain just bolting it on, with additional tuning you're guaranteed more. With my car the turbo (GT30-10) started to spool 300rpm sooner than with my ported 2G Manifold.
