Depends on who is making the jet kit for the bike. Screaming eagle is a harley specific make, dynojet another. Id recommend taking it to a Dyno centre or a specialist engine tuners and getting it professionally set up if you dont know how to adjust a carburettor. One example is Tim Blakemore Racing here in Bristol. If you have a newer fuel injected harley, the FI will probably sort itself out.

And no. Just change the pipes. I have an '08 FXSTC, I gutted the stock mufflers with a 1 1/16" hole saw. They sound great. What Robin does not know is that all ‘08 HD are injected. And no.

If you are going with a complete exhaust, I would also suggest going with a Hi-flo air cleaner and at least a download. If you are going with a complete exhaust and a hi-flo and have the extra cash, I would get a HD supertuner or Powercommander and have it dyno tuned Ace... you are going to screw up your bike. I would recommend getting some aftermarket slip ons at least. Stock pipes are tuned to reduce exhaust gas reversion. By drilling a hole you are letting hot exhaust gases back up the pipe and into the cylinder. This reduces exhaust flow, builds extra heat at the valve, and contaminates your air fuel mixture inside your cylinder. Now your bike won't fall apart or break down. However, you will see a loss of performance at lower rpms, and over time will cause valve train damage. If you are a putting a set of slip in mufflers on, you don’t need anything.
