I couldnt get my flowmaster 40 series to fit right so i took it down to my local exhaust shop and they directed me to a Vortex dual in single out muffler, designed for V6s. I have 2.5 off the cats, into the dual in muffler and out 2.75, 2.75 around the gas tank, and splits off into 2, 3", 24 inch Stainless Steal tips. The shop also told me that the longer the tip and larger diameter, the better sound. They did a real nice job with the tips, only making them stick out about .5 inches. For the whole setup it ran me 379, but only 100 was labor.
