The muffler deletes are more about freeing up the stock system, running them them with headers/etc. makes them even worse. I've gone the opposite route and tried to quiet my exhaust by keeping the stock midpipe and running a VERY quiet muffler, but its still very audible with the headers/frontpipe.

muffler deletes with headers/etc. makes them even worse soundwise? or peformance wise?
