For the price of the headers shipped the performance gains cannot be beat. It is right on par with headers that cost twice as much. On e thing to watch out for is that the headers don't have cats if you go with the longtubes. So if you are in an emmisions controled state these will not work for you. This was for a Pontiac G8 GT.

I had the local speed shop install these along with a steeda cold air intake and a dyno tune. With the existing magna flow street cat back system I already had in the car this set up put down 425hp and 383 tq to the rear wheels. The sound is amazing and the car is a beast now compared to stock with just a cat back exhaust. The shop said they were a little harder to install compared to the big name brand for twice the money, and the power Gaines were the same compared to other owners cars.
