G body tailpipes 2-1/2”
These pipes are great fit for my ‘79 Grand Prix, stock 301 V8 I ran duals from the manifold back with Summit type flow master mufflers. I had to flip them, offset in and out, the tailpipe side has to be outside and at a slight angle, maybe 15* or so sounds great now took out the dump truck throbbing!!! Nice mellow tone!!!!
