1964-65 Pontiac Lemans, Tempest, GTO, Custom V8 Dual Exhaust V8 w/NON-Stock RA or HO Manifolds


Waldron’s Exhaust has custom designed exhaust pipes that allows owners of  a 1964 or 1965 Lemans, Tempest, or GTO’s to use the Ram Air or High Output manifolds which were not stock in these model years.

  • Dual exhaust consists of the LS/RS exhaust pipes, LS/RS mufflers, and LS/RS tailpipes.
  • This system starts out at 2¼”OD on the exhaust pipes which reduce to 2″OD at the muffler inlets and then increases to 2¼” OD at the tailpipes.
  •  If the cast iron flanges are needed, add them to your cart for an additional $45.00.
    If you do not have a set of OE cast iron flanges, you may purchase a set of from Waldron's for an additional $45.00. If you already have a set, simply slip them on to your exhaust pipes once you receive your system.
  • All mufflers are built to the OEM specs. Our Mild Impostor's and Impostors allow you to keep your vehicle stock while changing your exhaust notes. Our Mild Impostor is a middle of the road turbo muffler, designed to give your exhaust a deeper, throatier tone. Our Impostor is a high performance, aggressive turbo muffler.

  • The following statement pertains to pipes only (mufflers have a 1 year warranty regardless of material chosen) and to vehicles that are not daily drivers and are stored in an enclosed building: Aluminized Steel has a life expectancy of 20-25 years and is considered to be truer to the original material on vintage vehicles. T409 Stainless Steel is ferric and magnets will stick to it. T409 stainless steel is the same type of stainless used by car manufactures today and will never rust through, although it may develop pock-marks of rust which can simply be buffed out.
  • When building our exhaust systems; where (or if) it requires a pipe diameter of 2” or larger, it will be 14-gauge tubing, where (or if) it requires a pipe diameter smaller than 2”, it will be 16-gauge tubing.
