My previous SS, I had the Alpha headers, CAI, and Variable Exhaust along with various other mods...
With the new Sling, I figured I am going to do more research (by research, ask more questions...) to be a little more picky on what I am going to add to the sling this go around.
With that being said... What makes one companies CAI and Header better than the other while providing a boost in performance? Would it be diameter of the pipe, the welding, or are they all pretty much the same and it comes down to finish and color?
The reason I went with ZZP header & exhaust
1. 2.5 inch, stainless header, designed for turbo / supercharger duty should I decide I need more power later
2. Race proven design. Kyle D did a pretty extensive thread on NA vs modded systems, adding one piece at a time, putting the sling back on the dyno each time. His precision and accuracy impressed me.
3. The catless design. Stock system has TWO catalytic converters, both generating tons of heat AND restricting the flow of exhaust and restricting engine power. The ZZP system gets rid of heat, AND improves exhaust flow with larger pipes and fewer restrictions.
4. The springless design. The ZZP header is a solid beast of TIG welded stainless steel. So solid that the muffler clamps right on with no other springs or clamps needed. Tighten ONE ring clamp (also beefy stainless steel!) and you are done. If you should ever need to remove the system, loosen the clamp (one bolt), pry the clamp open and the muffler comes right off. No special tools, wrap, filler, hangers, or springs needed.
The ZZP system is a marvel of engineering genius. No one else comes close IMHO, and the exhaust note is sexy as hell!
