TOGs are very good headers. Some people on here just base their opinion more on other people than real world experience (actually owning the product). Lots of people on here have a hard-on for Speed Daddy headers. The thing is to make them "Right" you would still have to have the downpipe re-welded. For the price that might not be that big of an issue for some people.
There are a few tips for installing them such as buying washers to install when you put the donut gaskets on both sides of the crossover. You should also put copper RTV around the donut gasket after you install the cross over to help it seal. You can also get a pre-bent dipstick from someone selling a few of them in the classified section. Other than that I have had no issues. The install is not that hard if you have the right tools and your not an idiot.
Some others will tell you that because the upstream O2 is too close to the bottom of rear header that you will have issues with fouling out O2 sensors all the time with TOGs. I have not run into this issue and run my car pretty well.
Good luck with the install.
