Seeing as how you have custom engine, there is no off-the-shelf exhaust that will be optimum. Best to build your own exhaust. Here's some reference material:
Performance Trends - Engine Analyser Pro - I use this for my turbo auto engines, you must be extremely precise with your measurements and inputs. Best to model factory engines first and make sure simulated dyno matches stock engine exactly. Then make modifications and upgrades https://www.centuryperformance.com/e...nd-length.html https://www.enginelabs.com/engine-te...gn-and-theory/ http://www.superstreetonline.com/how...om-made-header https://itstillruns.com/exhaust-head...n-8428151.html |
