    So, I had my kooks LT headers and catted H pipe installed over the weekend. Cost $430, which I though was very reasonable, and the guy did a good job and said he didn't have any issues with the install. I also have the Boral ATAK catback system so now the car is....wait for it....LOUD! Like...

    Hi everybody, I've been looking into buying some shorty headers for my 2012 Mustang GT. I'm debating between Kooks or BBK. I've noticed that the BBK shorty headers are cheaper but I haven't any videos on YouTube with anyone with a Mustang GT with those headers. I already know what the kooks...

    For whatever reason, still have a speed limiter. Could only do the select shift mode in 3rd gear because of it. On this Mustang Dyno, I hit 361 rwhp and 321 ft-lb of torque at 6600 RPMs. The tech said if he could have gone into 4th, it would have been closer to 370 rwhp. 2013 Mustang GT Kooks...

    So I installed a set of Kooks LTs with the Kooks catted Boss H-pipe and now when I go over bumps, I hear a squeaking noise that sounds like it's coming from the front of the exhaust. Any thoughts on what it might be? I've tightened down the exhaust bolts again, but have not messed with the motor...

    Are Kooks, Pypes, and BBK good brands for exhaust parts?

    Alright everyone. I've watched the videos on YouTube and I just cant decide. I've already made up my mind. Its either going to be the Borla ATAK catback or the Kooks catback. I want a nice deep muscle car rumble! Both sound awesome to me! I want nice and loud when I step on it but i want a nice...

    It's a good day. I am finally pulling the trigger on a set of Kooks LT Headers. I've been scouring the internet for install tips and recommendations, but I still had a few questions: Definitely use the OEM Gaskets on the headers, but what about the connection between the collector and the...
  8. SVT Cobra Tech
    So I decided to scrap my idea on rims/tires and get some LT kooks, O/R x pipe and some borla muffs. The things is, I'm confused (for lack of a better word) about the size I should get. I'm reading mixed reviews on the size of the primaries/collector. The 01 cobra is stock right now, but she...

    I spent this holiday weekend and tropical storm Lee installing my Kooks LT headers and catted H pipe on my 2008 GT convertible. I bought the hot jet ceramic coated Kooks headers/ H pipe combo from Maryland Speed last month and was waiting for this long weekend to install them. I started...

    I have Kooks complete exhaust system with O/R X-pipe and LT's. Firstly, Kooks X-pipe sounds like rice. Secondly, this is how it looks at 13K miles, 360 degrees exhaust leak :fuming:. H-pipe is ordered. Next time I will not go with Kooks.

    The car is in pieces AGAIN and I figured this would be a perfect time to do something about my underhood temperatures. I had contemplated sending my headers out to be ceramic coated but Sqidd convencied me, after generously offering to assit, to wrap them since it would be more effective. So...I...

    I just wanted to drop in and let everyone know that we picked up Kooks Custom Headers and we're really excited about it! I don't want to turn this TOO much into a sales thread. I will say that we're glad to be selling such a high quality product. When it comes to exhaust, Kooks is the best in...

    Thanks once again to my boy CR @ Tillman Speed in Aston, PA. We slapped a set of Kooks LT Headers 1/58" with catted X-pipe, to my existing vehicle equipped with SLP Loudmouths and Whipple S/C. The sound, INSANE and SICK!!!! Enjoy!! YouTube - 2005 Ford Mustang GT Kooks LT Headers Catted...

    Well finally got the car tuned after finishing my Kooks long tube header and catted H pipe install. My car is a 2007 GT and only has CAI and exhaust upgrade with Ford racing mufflers by Borla. My HP before the Kooks install was 282 RWHP and after ended up with 299 RWHP. The 282 was with just the...
