I have a 92 Subaru Loyale. 1.8 flat 4 non turbo with EFI. My exhaust system is trash...the only thing that doesn't leak or inst rust bad are the headers. I want to replace it completely but I don't want it to sound stock. I'm thinking of eliminating the cat and putting a high flow muffler on it. How important is back pressure? Will it run bad with little or minimum back pressure? Will it be more powerful with straight pipes and no cats? If you have any suggestions feel free to let me know
