One of our employees here, races arca late model mods, arca has restrictions on noise dbs, so he installed a dynatec vortex cone in the end of exhaust outlet, i can believe the differance in sound coming out of this 780 hp engine now. it gives it a deeper tone, not that crackling sound. you can google "dynatec vortex cones" i think summit and jegs sells them also, his just slid in the exhaust opening and was tack welded in two spots.has anyone ever used these on ff cars?

Trouble is they recommend them welded in the primary tube at the collector. Thst would mean buying 8 cones. Pricey.
May want to do a search on quiet exaust.Plenty of solutions have been tryed and used. Open headers if in the collector you'd notice a larger effect then in a ffr pipe.
