1981 BMW 320i 2 door sedan 5-speed. Rust free, San Francisco car.
Lowered on H&R sport springs and Bilsteins sports.
Dyno with mods, 90.25 whp, 91.24 wtq. Improvment of 5.72 whp and 4.39 wtq over stock exhaust.
2nd custom exhaust system - 2" mandrel bend, stainless, all held together with V-bands. Flex-pipe added to collector on my used Stahl header (had additional mount fabricated for collector to keep everything relatively still). Reused muffler and resonator, still no cat. Now much quieter cruising on the freeway.
