Ever since i got my LPP headers and the Y pipe was 3" i wanted to change my exhaust to a 3" but since the flowmaster was 2.5" also i kinda let it slip for awhile

Got some mandrel bend 3" aluminized tubing and ended using only 2 peaces of it, old exhaust was 2.5" with crappy bends , cleaned the flowmaster and the cut out and painted it with 2000f spray paint

Dont mind the welding, crappy harbor freight welder and welding once or twice a year thats the best i could do

 

Final product looks good. Mine sounded alot deeper when i went from 2.5 to 3" with my magnaflow.

 

Same here MUCH deeper, i didnt think it would sound that different, like it to far
