It also states that it will give you 10-15 HP, which is also hogwash.
Most parts on eBay are generic "universal" parts, which won't always fit with every car. Parts that are listed to fit multiple different models almost certainly were not actually tested for fitment, thus it's a bit of "buyer beware".
The only actual bolt-on exhausts/mufflers are the ones that you said were too expensive for you to buy.
Other than that, you'd need to get a system cut, bent, and welded at a shop. You might as well get quotes from the exhaust shops for how much it will cost to have an exhaust done properly, so you know what you're looking at in case noone can install that muffler.
