1970, 1972 & 1974 Mercury Full Size 429ci & 460ci V8 Partial Dual Exhaust


This listing covers MY 1970 (with a 429ci) 1970 & 1972 full size Mercury with the stock 429ci and 1974 full size Mercury’s with the stock 460ci. Mercury did not offer dual exhaust systems on any full size cars in 1971 or 1973.

No aftermarket company ever reproduced the H pipes for these MY’s and so we are unable to offer the complete system. If you have an original H pipe and would like to have us use it to reproduce your system, please contact us. 

  • We can help you out with the LS/RS mufflers, LS/RS front tailpipes, and LS/RS rear tailpipes.


  • 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.
