I have them on my car. Not a great fit at all. As Roller pointed out, driver side fit fine, passenger, not so much. I ended up banging the 1 tube pretty good and notching a bit of the lower control arm mount. I plan on cutting a portion of the 1 tube and snaking it in there a little better.
For the cost of the headers and a little fab work I will have to do, the price is tough to beat. I believe others have said the pacesetters aren't bad and are not really expensive.
