Will the Hard Kore Quiet Baffles work with the Vance & Hines or Cobra Quiet Baffles ?
Yes. Smartpartz Hard Kore Quiet Baffles were designed and tested to work with your original baffles and this is what we recommend. They will work with the Vance & Hines Quiet Baffles but this is a more restrictive option.
Do I need to rejet ?
Extensive testing has shown that the Smartpartz Hard Kore Quiet Baffles in most instances produce a slightly richer condition (less than 1%) which does not require rejetting unless you are bordering on too rich already. Motorcycles over 1100cc requiring the 2", 2.25" or 2.5" baffle styles are more likely to produce a richer condition. In some circumstances leaning up the fuel/air mixture screw slightly is sometimes all that is required.
Will I lose power ?
No. Smartpartz Hard Kore Quiet Baffles create more back pressure for the engine and many riders are noticing that their bikes are running noticeably stronger through the mid-range as a result.
What other effects on the sound of my pipes are there ?
In many cases the popping on deceleration is reduced or totally eliminated after installing the Smartpartz Hard Kore Quiet Baffles, producing a nice rumble.
Do I need to remove my original baffles ?
The Smartpartz Hard Kore Quiet Baffles work with your original baffles in most cases.
I have installed my Smartpartz Hard Kore Quiet Baffles and I notice a slight rattle. What should I do ?
Your Smartpartz Hard Kore Quiet Baffles need to be inserted squarely into the exhaust pipe to ensure the Smartpartz Hard Kore Quiet Baffles do not make contact with the original baffles. It is important that when you measure from the Smartpartz Hard Kore Quiet Baffle to the end of the exhaust pipe at various points aroound the exhaust pipe, the measurement is exactly the same at all points. If the measurement is off by 1/8th of an inch, this makes nearly a 1/4 inch difference at the tip of the hard kore baffle which could lead to a rattle. On the 2.75"s, there is sometimes a machining burr on the original baffles which prevent our baffles sitting squarely. This can be easily cured by grinding the burr off.
Why do I need to drill a hole when there is one there already?
The original hole is a threaded hole and the hole in our baffle is also threaded. To screw through two threads can cause one of the threads to bind.
How do I find the exhaust pipe part number on my Hard Krome pipe ?
This is stamped on your front pipe, on the first bracket (which attaches your outer and inner pipes) approx 6-10" from the engine head. Slide a mirror between your front exhaust pipe and engine to view this. Remember the mirror will show the numbers in reverse.
