Ive had my 2006 Tundra 4x4 regular cab since december of last year. Im wondering has any body Installed JBA headers on there 2006 tundra tundra. JBA s website show a gain of 21.8 hp at the rear wheels. Ive read a lot of the old posts concerning the vvti engine . I would be grateful to hear from somebody that has installed the jba headers on there 2006 tundras. Im thinking of pulling a eighteen foot travel trailer . I would like to know if a set of the jba headers are going to make that big of a power difference . Thanks in advance BB KID :tu: :tu:
