Hedders: Old\'s 77-80 w/ 403 V8
Reviews

These are the best fitting hedders we can locate for the 403 Olds, LHD or RHD... as found in the 77-79 Firebird TA series.

Black steel hedders from a leading Exhaust USA specialist.

These headers are computer bent and leak tested, have die-cut exhaust port flanges, and machine formed and hand welded primary tube ends.

  • Most importantly.. they're specifically made to the LHD 403 Olds as found in the Firebird & Trans Am series.
  • In RHD converted cars.. these have been the best hedder result found......NOTE THAT IN SOME... maybe 5% of cases... a narrowing of the RHS 1 & 2 pipes CAN BE NEEDED.. ie . about a 1/4 inch cut and shut in the piping.. but its probably $1000 cheaper then getting an exhaust place to assemble a collection of pipes in a none flow type fitted arrangement.

    In the majority of time.. and that's 95%.. there is little alterations needed, but we  don't guarentee  that.. it can depend on the conversion.

    BE AWARE .. there is NO refund on these headers... they are correct.... These are correct for LHD cars and the best we can obtain - after a lot of cost & time in trial and error... for clearances on RHD conversion.. MOST.. conversions. In about 5% of cases there will be pipe minimising to do... but still a lot cheaper then getting a bunch of non-flow tested pipes welded together that resembled "headers".

    Unfortunately ... due to infrequent scams... we also HAVE to take the following stance as in the past.. certain people have purchased them from us.. had pipe benders template them & then simply return ours claiming all sorts of reasons... but have used the headers like a lending library .... returning to us stuff that has been fitted, pulled apart & looking like junk when the packaging & contents are returned. We don't lie about product & we don't give people second rate crap.. never have and never will. There is no return on headers period.. so choose carefully please..

    There is NO exception to this rule.

    This is the best outcome for all .. or pay a BUCKET load more to try and get something made up etc.

    Heavy part..  Delivery additional.
