1970 DUSTER 340 FACTORY EXHAUST END CUTS w/o TIPS???

I would certainly think there would be difference from a 1968 Barracuda and the "high performance" 1970 Duster 340 included in the Rapid Transit System along with the GTX, RR, 'Cuda, and Sport Fury GT. The 2 1/4" all the way back was STANDARD equipment for the 1970 Duster 340.

My Barracuda is an original 340 Formula S car. It is High Performance.

I don’t see anywhere in the RTS ads that say full 2 1/4” exhaust

Accurate LTD offers 2 1/2” , 2 1/4” and 1 7/8” tailpipe outlets. They don’t say which is OE.
