Lucan 196 Report post Posted October 2, 2018 Looking for some advice, going to build my own exhaust to keep funds open for other repairs/upgrades on the E30. Dont want an obnoxiously loud setup and have the following available to use: 3.2 E36 M3 Muffler E36 328i complete exhaust from headers to muffler (probably won’t need) Will buy piping/bends as required. Idea at present: as the M3 muffler has dual inlet 2.25” pipes I’m leaning towards 2 y sections, 1 after the headers and 1 pre-muffler. With 2.5” center section to keep it simple and reduce weight. I don’t see any real benefit to a dual exhaust? Yea? Quote Share this post Link to post Share on other sites
