Summit headers and "half dummy" zoomie pipes

So are you going from the 3"collector transitioning into a 4 way splitter to 4 individual pipes?

Cause it'll look cool and sound sweet but the collector having a diversion splitter close to it will really kill flow and scavenging. It will have reversion waves reflecting back up the collector towards the engine.
Best to have 3" gently curved then ovaled from your collector pointing out from under the car and up at a 30 degree angle. Then when you floor it you can see flames launching onto civics as you pass them.
