Report with or without HO or RA in the order form below. If you have a RA or HO set-up and need the cast iron flanges, you may add them to the cart.

  • There is an additional cost of $89.00 for HO & Ram Air systems due to the larger pipe diameter.
  • Price: $45.00
    All HO or Ram Air systems require cast iron flanges and Waldron's Exhaust will need to have them PRIOR to our building the exhaust pipes (due to flat spots). If you do not have the needed cast iron flanges, add a set to your cart here. If you already have them, please send them to us at: PO Box 99 208 W. Main St. Centreville MI 49032
  • All mufflers are built to the OEM specs. In order to reproduce the OEM sound level on these Firebirds, we use the Mild Impostor design. 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.
  • Check out our On-line Swap Meet for both aftermarket and OEM (some) H pipes and Y pipes, along with “odd ball” mufflers.
