no question for the money they are a great deal. Fitment and welding is good. We dynoed these compared to Greg dupree (which we also sell) and found that at the stage III level there is a 10 - 11 ft lbs midrange torque difference at 18 psi boost, single pop 555 inj in favor of the Greg D's. $150 vs $650 (GD test pipes and downpipes)is a huge difference BUT just a FYI WE still use the GD stuff on our cars. My guess is the NEW GD version will be better still. I'm ready to order the new version asap Harry
