Note: Please see U.S. EPA and your respective state and local regulations to confirm noise and emission compliance.

Important Exhaust Notes:

• Note: With any new exhaust, we recommend changes to carburetor jetting or use of an aftermarket fuel injection control module.

• There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Blueing is caused by tuning characteristics, cam timing, carburetor jetting, overheating, etc. and is not caused by defective manufacturing. No refunds on exhaust pipes once motorcycle is started unless there's a manufacturer's defect.

Cobra 909 Slip-ons
I had Neighbor Haters on by previous two-wheeler so I knew it was necessary to upgrade my 2020 Tri Glide with these slip-ons. I also upgraded the V & H VO2 induction and added the FP3. Runs and sounds real nice.

Great deal on Corba mufflers. Fast ground shipping. Only one problem. No tracking number for package. Thank great service and good deal

these are exactly what I was looking for: a nice deep rumble that doesn't get on my nerves on long trips and doesn't irritate everyone riding behind me.

I’m happy with the new pipes. They produce the deep Harley sounds i was looking for.
