At my ford store putting them on. First thing I'm seeing is the absents of thermal wrap on the PPE's. Going to continue and if we think it necessary, I guess I can just wrap them later. Also writing Steps  and taking photos
 
Super news... congrats!

Heat is a concern I have.  I ordered the thermal coated ones.  dyno testing of one versus the other is planned tentatively for about 1 Mar to see how much difference, if any, it makes.
 
Wraps not recommended, they have been known to trap moisture and lead to rust.  Go with coatings instead.
 
Was thinking more like shield blanket wrap type, not tape. Anyway got it done. Had to weld a new bung on and fix another. I'll get more detail in a bit just thought I report completion. Ice and snow pretty heavy but I can tell there is a lot more throttle response

So you had not problem with fitment on your car? Everything bolted right up?
As far as wrapping, reason to, the downpipes run cooler than stockers and cool much much faster than stock pieces.
 
@ Shodded, I should probably install and test them before I even *think* of making another set. I'll do that tomorrow after work 8)

Keep SHOded's comment in mind for all components, especially in the northern climates. Even if it's just the bolts rust is a nuisance! Not a fun place to be drilling and tapping!
While the thermal coating is different, and common sense tells us that it should reduce underhood temps and increase performance, I may have dynos and temp measurements to share later this week (possibly tomorrow night) comparing this with OEM.  It should at least give you a real world example of what you might expect so that you can evaluate bang for the buck (WHP and torque anyway... really don't want a "bang" LOL).
 
Which brings to mind another thought.  If the OEM fasteners are not stainless steel, might be worth it to source equivalent SS fasteners to secure the future.  Really handy in the Gen 1/2 SHO exhaust systems!
 
The heat 'shield' that Ford uses wont really trap much appreciable moisture IMO, the thermal 'wraps' on the other hand do. My bro wrapped his entire header on his early 2000's Yamaha YZF 1000. Not sure how or exactly why(scavenging, velocity, heat control?) but it actually made his bike faster. We had made dozens of side by side pulls against my Honda before and after and he was now 2-3 bikes further ahead by 120MPH in the exact same pulls so even other than controlling underhood/undercar temps, its an actual power making mod on a naturally aspirated motor. Thermal coatings BEFORE the turbo (exhaust manifolds) on a turbocharged application will also make more power and spool the turbo sooner by delivering more heat energy to the tubine side of the turbo.  There are some steering/suspension components that run near the rear DP and the front cat is fitted in there pretty tight so  I think heat shields are a good idea in those spots.  BTW, the exhaust headers on my Bro's Yamaha rusted thru a bunch of pinholes within 2 years and he had to replace the entire exhaust.  He still has that bike and I miss my CBR 900RR :icon_cry:
