The '65 HP Exhaust can be ordered from Year One. It includes the correct Y Pipe, Intermediate Pipe, Muffler, Smashed on one corner, the over rear pipe over the axle, plus resonator with Tip. You can order just the resonator with tip, or the resonator by itself.

IMO, you cant beat the sound on with any small-block exhaust setup. Got that low rumble thats unique to the early A-body 273..

I replaced the old HP Exhaust on my '65 Dart with the year one reproduction, and except for a simple mod I made with my Vise for where it clears the front sub-frame, it was pretty much perfect match what I took off the car.
