Never heard of them bud If you want cheap and a reputable brand we know then Pacesetters aren't terrible, they aren't great either, but they are cheap, pypes and even mac is cheap... Cams will get you to 320ish with where you are at now.
dont get something you dont know.. Pypes brand is cheap enough and I found out a few weeks ago that pypes will actually give you more power than mos of the others. obviously if you spend 1300 on just the LT's there is a reason but basically pypes is just a little less quality metal.. but apparently are better.
Id recommend them and an x pipe and then the cams. But up to you obviously its your choice. I wouldnt go with something Ive never heard of off of ebay. But thats just personal
I'm going to have to suggest tweaking up your suspension a bit to increase the fun factor and the control of the car, alternatively if you want to firm up the drivetrain and get good performance returns for your investment a one piece lightweight driveshaft should be in your future.
Best of all neither mods require tuning
...thought technically an alignment could be considered just that.
Keep looking on ebay, for about the same price I found the Pypes headers with an off road x pipe for I think 600 or 650. That in my opinion is a great price.. Ill try to find the link again..
Here you go.. I was wrong on price, its 680, but still a good price for a better product. Again I say spend the extra money on a better part and you will be a lot happier. You get what you pay for and thats how you have to look at it. The better the product the better HP, Torque, and your car will run (in mossssst cases haha)
Good luck with everything. I really hope we all helped, and everyone on here is intelligent when it comes to products and mustangs so your in good hands. I know they have helped me.. Im debating going with either headers and x pipe, or cams next.. HAAAARD decision! lol.
