have anyone of you ever used a tuneable muffler or a muffler with a silencer that you can put in to it to quiet it down? like greddy or arospeed? could any reccomend one for me i had a neuspeed and it was so #$%# loud in the car but i like how the took off when i was doing highway speeds.

 

a friend of mine has the dual n1 mufflers. you can't hear anything but his turbo winding up, even at full throttle. i haven't heard it without the silencers though.
