So it has too much backpressure?? Even though I went form a single exhaust setup with a muffler (witch mufflers produce backpressure) to a duel setup, which has more piping and probably all together would equal about a 2.5" exit (combinding the 2 pipes into their square areas). Sorry if I talk stupid, but I'm not firmiliar with exhaust too much. Anyway, how bad is it to run my car this way if it has too much/ too little backpressure
