Yes it does, but here is what I noticed.

Bike sounds more aggressive and it has a more crisp throttle.

Only mods it has are:
1 - K&N filter and snorkel removed
2 - Long Triumph pipes debaffled

So the $ 230.00 for a new Sparker TCIP4 was not bad. Got it directly from manufacturer.

I will compare it to the stock one when weather conditions are better.
