Have done quite a bit of browsing and think I have a plan. Looking at Magnaflow muffler # 12579 and converter # 95509. If anyone knows of a great place to buy these, let me know. Otherwise will send to i-ether Monday. Will try to use existing pipes as they are still OK.

Tip: When shopping, also look at K3500 pickup parts. Sub often only lists 5.7L stuff.

Kennedy Diesel will bend a 3" or 3.5" tailpipe. Stock is 3". Doubting the 3.5" would be worth another $150., when other parts of system are 3". Kennedy or Walker offer 3" for about $ 79.

Y-pipe is a long, expensive looking assy that I have not found any source for other than GM.

Also can't find any shorty resonator tips. Thinking of 3" in 4" out or split, 8 - 12" length. Monzas are too long. Maybe use a SuperTrapp if it's too loud.

Suggestions? (Cat after muffler, single system.)
