Re: extractors & exhaust
For extractors.. Pacemaker race series are pretty damn popular, JMM headers are basically a rip-off of pacemakers (apparently) so they'd be just as good.. avoid Genies, they get a lot of bad / mixed reports in my experiance.
As for exhausts.. Lukey or Redback I guess..
Note that extractors/exhausts aren't a do-it-yourself item, unless you have the ability to weld, so expect to cough up a bit extra for the installation.
TQE, SWB, ATPS, Worst of the E-series.. and I wouldn't have it any other way
