Ok i have a 96 ls non-vtec teg. I am planning on buying some type of DC header maybe DC Sports JDM 4-1 header, but i heard this header is a few inches longer, so I may need to trim a section of exhaust. It has a 2.5" collector. Which exhaust would be best for the performance and would fit a 2.5" collector? I am also thinking of getting a stress pipe.
