SOLD
These came off my LT4 and are in excellent condition, as the car had only 21k on the clock when they were removed. They've been stored in a cabinet in the garage ever since and, as a bonus, prior to posting them FS I hit them w/ a few coats of Hi-Temp Black Exhaust paint. I think $50 for both mufflers is fair & shipping (1 box @ 41 lbs.) will be somewhere between $25-$40 (depending on locale) so $80 shipped seems reasonable.
