I just installed Stainless Works headers and their True Dual Exhaust system with SE's 5" chrome outlets, by myself, on my present "03 SSR. It was easy and cost me about 8 hours to install plus another 6 hours aligning everything afterwards. I had installed SW headers and TD exhaust systems on my previous '04 and '05 SSRs...…. great craftsmanship from SW and SE. NOTE; I did use a lot of heat shielding. Just my $.02.
