Muffler

The previous owner installed a noisy Thrush muffler on my '68 Dart 225. What Walker muffler would be a suitable quiet replacement?

Can you tell if it is OEM sized front and tailpipes? I can look up the right one if I knew...

A quite muffler from Walker would be there “Quite flow” line.

Exhaust pipe is 1 7/8" OD, tailpipe is 1 5/8 OD.

This is the closest I could find in the quick;
Walker Exhaust Mufflers - 1.875 in. Inlet Diameter (in.) - 1.750 in. Outlet Diameter (in.) - Center Outlet Location - Walker muffler KEYWORD - Free Shipping on Orders Over $99 at Summit Racing

More data. I'll see if I can find the correct new muffler number from Walker.

Rumblefish, as usual, is right on. The one suggested is 21.5" overall length as is the OEM one. And inlet and outlet bushing sizes are right and it is cheap!

Thanks Tom. I wasn’t 100% thinking that was it but it seemed to make sense and about fit right.

Thx gents. The prior owner did such a poor job of installation that the pipes are loose in the hangers and the clamps allow the pipes/muffler to rotate! I'm soaking the exhaust manifold bolts in penetrate, so the whole assembly should be easy to remove. The exhaust pipe and tailpipe are rust-free, so the job should be low-cost.
