Mufflers choice ?

70 Dart, 370 hp 360 magnum, with a 150 shot of gas
Dougs D453 headers
Looking under the car for clearance for the mufflers, it Looks like offset inlets/outlets
Might provide best clearance versus straight thru.?????
3 inch collectors, 3 inch pipe all the way out the back is the plan
Im listening to ultraflow welded, and super turbo sound clips
I must be the old man out.
I went with 3" electric cut outs into 2.5" Pypes X pipe,Street Pro Mufflers
, tailpipes with a stock style 2.5 SS tips
The Street Pros sounded fine enough to me.
They market a 3" exhaust and mufflers in A- Body as well.
