Question: I am interested in ordering a set of Roadburner pipes. Is there anything I should order with these pipes?
Answer: There are two things we recommend along with a set of Roadburner pipes.
 For the Carbureted Models – The first thing we recommend is to have the bikes jetting recalibrated.  For the Fuel Injected bikes – We recommend the addition of a PowerCommander.
The other thing we recommend with a complete set of Roadburner pipes is to replace the crush gaskets.
Question: I am interested in ordering a full set of Roadburner pipes. Do I need to re-jet my motorcycle in accordance?
Answer: If your bike is carbureted we recommend the Dynojet Stage 1 jet kit for our pipe applications. The bike could run lean otherwise and you could experience a pop on deceleration. The jet kit can be purchased through your local dealer.
If your bike has Fuel Injected, we recommend the Dynojet PowerCommander. The PowerCommander will alter your air/fuel mixture. Your stock F.I. can compensate for only a small spectrum, NOT enough for an aftermarket exhaust. The Power Commander can alter that stock map and can be re-programmed for modifications installed at a later time.

Question: I have installed a complete set of Roadburner pipes on my motorcycle. On deceleration the bike pops, how can I fix this?
Answer: A pop is usually in indication of one of two instances.
 The most common is that the bike has not been jetted, or was jetted incorrectly.  The other instance is a crush gasket at the head.
This is an OEM part. This crush gasket is a one-time crush, similar to a spark plug seal. We recommend replacing this gasket when installing new pipes. There is a chance an air leak at the head/ exhaust junction can lead to the popping. The crush gasket is an OEM part and available through your local dealer. We do not offer this part.
