Do your pipes have O2 Bungs? 

Yes!! All of our pipes have 18mm bungs in them, so you can use aftermarket wideband sensors or factory sensors. If your bike came from the factory with 12mm sensors, you will need a 12mm-18mm Sensor adapter.  If your bike doesn't have  O2 sensors you will need a 18mm sensor plug. you can request Custom pipes without sensor bungs if you so prefer 

Does your pipe come with 12mm-18mm adapters?

No. You will need to get 12-18mm adapters from your local dealer if you are running the small style sensors. 

What kind of performance gains?

Our Exhaust systems will provide performance gains across the RPM Range. The results will vary based on Displacement, Compression and General Performance modifications done to the motor. Please refer to our Facebook/Instagram for dyno Graphs we post. or email is @ 

Do your systems include exhaust port gaskets?

No, we suggest Screaming Eagle Exhaust Gaskets from your local Harley Davidson dealer.

Can I repack my muffler?

Mufflers with our removable endcap can be repacked to your liking with a variety of packing. they come packed with Stainless steel wool, but fibreglass and other options work very well and change the tone of the pipe. 

Our Sealed cap mufflers are Non-Serviceable 

Do you make custom exhaust systems?

Yes! Contact us at for all custom inquires 

What if my pipe breaks?

We handle warranty based on a case by case basis. Unless the pipe is obviously broken from a crash/hit/dragged, then we will happily issue you a Warranty repair or replacement if it is in a reasonable time period. All warranty or repairs require the item in question to be sent back to Sawicki Speed Shop before a replacement is sent out.
