Dual Exhaust Vs. Larger Single October 08, 2006, 01:38:47 AM I have been comptemplating putting dual exhaust on my 86 Cougar and i just read an article on CoolCats about using a larger bore single exhaust as an alternative. what would be the advantages of either one? I know that duals are cooler in general than a single, but would the larger bore single have a similar power advantage with less cost? Quote Selected
Dual Exhaust Vs. Larger Single Reply #1 – October 08, 2006, 02:55:54 AM single 3" would be better if you have to have a stock style. Dual's would be cheaper because you dont have to make the bends as tight and you dont have to have every single peice custom made or fitted. Quote Selected

Dual Exhaust Vs. Larger Single Reply #3 – October 08, 2006, 09:22:42 PM A larger single would benefit you but dual would be better because each cylinder emits a pulse of exhaust gas and if it all merges into one single pipe, the pulses will interfere with each other and create more backpressure. Having an H or X pipe makes duals even better because the exhaust can switch over to the other pipe if there is too much restriction. That is just my intuitive thinking. Plus dual exhaust would sound better and look better too. Quote Selected
