as many of you know our cars exhaust is very quite in the higher rpm range. i installed a ebay muffler and loved it, but after 4k, i couldn't hear it anymore, so i cut of my resonator, it help alittle, but not much. so i removed the second cat, and let me say its freakin awesome now. its raspy, loud and the high end pulls alittle better, but still sux after 6k rpm. the can actually hear the car idle now. if you don't like the loud volume, i wouldn't recommend this mod.

 

Couldn't hear it after 4k rpm? That's about when my Mazdaspeed exhaust really starts to sing. You must like it LOUD.

 

same here.....its audible and quite nice up to about 4K....and after that it starts to get pretty loud....I like it....but I need to crank up the volume just a tad more....lol

 

if i could afford the MS exhaust then i guess i wouldn't of had the problem i had! owell, i'm only out 50 bucks comparted to 350(i don't know what the actuall price is)
