  • Dual exhaust consists of the LS/RS exhaust pipes, LS/RS mufflers, LS/RS connector pipes, and LS/RS resonators with turndowns.

You will also be asked whether you have the cast iron flanges or if you need them added to your cart. If you already have the needed cast iron, you will need to send them to Waldron’s in advance.
  • 1966 & 1967 resonators are bullet style while 1969 resonators are cannister style.
    We will need to know what type of manifolds you have. If your vehicle has RA or HO manifolds there is an additional $50.00 added to the system cost.
    The OEM flanges for the Ram Air or High Output systems are cast iron and will be needed in advance of our building your system (if you have RA or HO manifolds).

  • 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.
