Hi to all, Reading this month's Mopar Muscle (Jan '04 issue) - page 90 "New Products" I see mentionned that: "the new addition to the TTI exhaust line for the C-body ('65 to '73) are these 383 and 440 1 7/8" headers and 2 1/2" or 3" exhaust with Dynomax mufflers . They are designed to fit stock cast-iron cylinder heads or Edelbrock aluminium heads, and the exhaust systems are available for wagons and passenger cars". Tube Technologies (909) 371-4878 www.ttiexhaust.com Just what to ask Santa for the 300L ? John
