Tsudo is a ripoff of Skunk2 usually. The exhausts made by both companies suck, so look for something made by someone else. If you want specific brands, you need to search this site.

But since you have only $250, I would either recommend a) buy a muffler and have a shop make you a custom exhaust or b) keep saving for a real exhaust. I prefer option b since it will sound and look better and you will actually gain some power from it. If you insist that you need a fart pipe right now, do option a.
