Didn't bother buying a Invidia or Skunk one, the local exhaust shop here fabricated one for me.

 

Ehh, I've been running my v3 n1 duals for 2 years and 1 year on the TP. Let that thing break in and you lose a lot of that raspyness.

+1 on the loud factor, it will be too loud for music once installed. Give it maybe a thousand or so miles to get a carbon build up and it will have a more defined tone.

It gets nasty loud at wot, cops will definitely know your around if you show boat.

I've learned its db range is loud on the low end if you gas it, around 3500 it gets quiet up until 5K.. the rest is.. you know....
I take advantage of any road that has a structure of some kind covering all sides except the one in front and behind you.. It is pure

I DD on this exhaust with TP also. Its something you will get use to..

 

When the engine is cold it is freakin loud, but quietens down a bit once the engine temp has increased.

 

i have an invidia tp with cel fix 110.00 shipped and im using a berk tp with a custome 1 off exhaust system mig & tig welded, powder coated with high temp powder coat and finished off with an Apex n1 muffler with the same powder coat treatment. Gotta say wow~!~!~!~!!!! i havent heard a bike or car that tops the drone and loudness of this system along with burps of smoke n flames!!
