got my dyantechs installed also and I have the borla touring axle back and rotofab intake and i have no drone on the highway....
I am very pleased. car sounds healthy and when you nail it it screams!!!
was driving today and floored it and nearly got caught by a motorcycle cop coming the other way i was in second gear and quickly let off the gas when i saw him and I put it in neutral...I know he heard me, he looked over as I went by but he let me go....whew....close one.
anyways anyone want a good install at a great price in central florida, see this post
