Vivid racing was burned at the stake a while back over some BS here on the forum. They made a mistake in posting some dyno results and people jumped on them and said Vivid was trying to lie about the gains made by their products. It stemmed from a severe over reaction by a few forum members in my opinion. Anytime I contacted them they were very helpful. As far as fitment issues, EVERY exhaust company has had issues.
The products you listed are on the cheaper, and therefore, lower quality end of the spectrum. If it is what you can afford then that kind of solves the problem. If you can save up a little more money I would suggest buying a higher quality product.
As far as vivid, I would have no hesitation buying anything from them. They are good peoples.
Just my 2 cents.
