Photo depicts the  system for 1970-72 Firebirds (Non HO or Ram Air).

  • Dual exhaust system consists of LS/RS front exhaust pipes, LS/RS rear (over-axle) exhaust pipes, dual in/dual out transverse muffler, and LS/RS tailpipes. Designed to fit with the stock chrome tips which are not included with the system. 
  • The standard engines take a system that starts out at 2″OD on the front exhaust pipes (with 2blt flanges), then increases to 2¼”OD on the rear exhaust pipes, and reduces back to 2″OD on the tailpipes.
  • The Ram Air or HO systems are 2¼”OD up to the muffler inlets and then reduces to 2″OD on the tailpipes.
  • You will be asked to report with or without RA or HO manifolds along with bolt pattern needed for RA/HO systems in the check out process. There will be an additional cost of $89.00 for the Ram Air / HO systems. If you need the cast iron flanges, you may add them to your order in the check out process. If you already have the need set, you will need to mail them to us in advance (address is shown in the check out form). 
  • 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.

Description

  • Our exhaust systems are made to order. For our current lead time, please refer to the gray banner above.
  • For orders shipping within the 48 USA contiguous states, the shipping charges will calculate correctly. For orders shipping outside the 48 USA contiguous states, please submit your order without payment, we will get in touch with you with your shipping options and get your order completed.
  • 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.
