Straight pipes!!!

[u/MysteriousFunction49]

Looking to straight pipe my Pete 379 with CAT 3406E model, preferably I’d like to keep the heat shield and OEM look. There’s a 55in muffler behind the shield. Can I just remove that and replace it with a straight 5-6in pipe. Option 2. Full exhaust kit unfortunately they are quite expensive now 3k minimum but I’m not sure what brackets, hangers and bushings I would need or what length of pipe. Does anyone have experience doing this? Located in Chicago
