I like loud, i have slp high flow cats now, on my stock y pipe, i plan on installing thorley long tubes. I have the oppertunity for a custom true dual setup, so i'm wondering what muffler i should use. I'm considering the magnaflow dual in/out with the x core, anyone using this ? i figure get the x and muffler outta the way at the same time... with my cat's is this useless? also, dynomax ultra flow has a dual in dual out muffler that's a straight core design. anyone using this? or should i just go with two straight core mufflers? ultra flow probably being my first choice. other suggestions and all comments are welcome. thanx guys....

 

go with hooker aero chamber, trust me
