A bit of an enigma going from the best product I’ve seen / heard and rave reviews to poor customer service.
HM (makers of HSV tri-y headers) is now liquidated, PaceMaker don’t care about customers only resellers, resellers care more about business than product.
Genie and Wildcat are real, not much presence, Manta gets a good show with their mail order rep spruiking here, as does Hurricane.
Difilipo is overhyped, overpriced and caters for the old school sound, X-force is a clever Chinese trap! for young players... but there are some good independents in most cities still.
