spiral flow vs 1 chambers which is louder?
i want to go to true duals and want to use the spiral flows but i don't want them to be to loud
I have a custom exhaust with a force muffler. It sounds mean as hell through the muffler. But when I open the cutout, people think the car is possessed by satan himself!

But to answer your ?
Both will be loud. The sprial will be more tame and bassy and the flowmaster will probably sound alot meaner and cut the rasp better.
But they are both going to SCREAM @ WOT!!
