  • 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.
