John, I am currently considering changing both my headers and sidepipes on my BB 406. I would like to go to a 2" header and 3" sidepipe. So far, Firefly Performance is my leading candidate as they seem to be good quality, have read some good reports, and understand they're made for the SPF. However, because of price I plan to see them and hear them first before I jump. My builder said I can do the driver's side with just removing the heat shields. I am still looking at options, but want to do something by Spring. So far my stock ones look fine, but they only have 2500 miles on them.

Good luck with your change out!
