Got them from tillman speed in the states. And it was a gong show getting them as well. First off they sold them to me when they had a set in stock, then after a week or two I found out they sold them on me...it was another 2 months before I actually got them. Because thats when the new camaro came out so the mustang stuff got put on hold for that.

As for the price I couldnt actually tell you but 1600 doesnt sound too far off. Don't order from Tillman, unless you wanna call there every second day to see where your order is at. They are understaffed and arent real worried about orders under $5000.00...that might be a little excessive but you get my point. Good luck.

'08 GT premium 5 spd

just a couple little things

Anyway I am still having a misfire at part throttle in 4th and 5th gear and sometimes in 3rd.

Would a temp gun be able to pick up a bad coil? If the degrees are off by 5 or more?
Take a look at this maybe it will help explain what I mean:

Too much to list and nothing really that great. If interested check out my profile.
Numbers are just that...numbers.

Sorry for the very late response. The latest news about the car...
Changed one coil and all the spark plugs. The misfire is gone. I gapped the plugs to 0.035 and the ones that were in there were at the factory gap.(0.045)

I found additional problem. My iat's were averaging 175 degrees and noticed that the pump for the intercooler was not operating properly. I tracked it down to a bad ground. When the pump is working properly you should here it with the key on. (I did not know this because I wasn't sure what kind of duty cycle these pumps operate on) Now my iat's are staying around 115 degrees.

I figured it out and finally pulled a [email protected] mph at the track. I'm going to the track tomorrow to see what I can do with the new headers and magna flow cat back.

Don't know if you are still looking for some Kooks headers but if you are Unleashedbeast gave me a heads up on some kooks LT with catted h-pipe from Maryland Speed. Cost was around $1300. He also posted a code that will get you ceramic coating for free. Have ordered mine and they are at the coaters now. If you do a search on kooks or on the user you can find his post
