I am looking to do a muffler swap on my 2010 Titan and am not sure what one to go with. On both my hot rods I run spintech and love their sound, but have yet to hear one in person on a Titan (videos i know don't always sound the best). I am not a flowmaster or magnaflow fan so those are out. On my race car I had the dynomax race bullets but they were horribly loud and blew out quickly. What would you guys suggest for a good muffler and what configuration do I need to buy? Seems that I have a dual inlet and single outlet muffler but have been having trouble finding mufflers in that configuration.
