Got mine on Saturday, dropped the car off at the shop this morning. Hopefully in a couple of days I'll have some good news...

Someone posted a dyno chart recently, and these things give over 30 hp boost and over 30 ft lbs of torque!

Awesome!

Still have a few IN STOCK.

Remember, after this batch is gone, it's going to be 6-8+ weeks for more to come in, so if you are on the fence, order soon. I will update the site when they are out of stock.

Just my luck....After this GB I have started to notice one of mine is making the cold start tick. If anyone decides not to install there's please let me know.
 
Just going to give everyone that buys these headers a heads up. You will need to cut and weld your catalytic converter onto these headers. When you get the headers, there is no flange for the exhaust. Also, purchase new exhaust studs and nuts.

Pretty sure that's been stated over a dozen times. Also the directions have been posted on here as well.
