I am currently rebuilding my 1986 Rx7 Gxl, and need an exhaust since the previous owner thought it would be a good idea to cut half of the manifold off. I am planning on building a my own and would like to know any recommendations for how i should properly go about it I do plan on putting a cat on it to for visual inspection when i go for emission and and possibly a dual exit and mufflers for inspection. i am looking a somewhat loud deep tone, something will make people be like damn thats loud but sounds good, i was thinking of doing 2.5in piping to a 3in muffler but i would love to hear any recommendations on what header, mufflers, and resonators i should run, do keep in mind that im doing this on a budget. thank you anyone willing to help
