Got a great price from J&P. Pipes are as described, simple to install with good directions, and sound AWESOME!

I had my Cobra Exhaust pipes put on my 2007 Honda 750 Shadow Aero about 5 years ago. Along with a stage 2 Cobra jet kit. My bike performs alot better than it did from the factory. Sounds 100% better. I would highly recommend these items if you want more get up and go.

Great looks and sound. Fits well with stock C-50 Boulevard saddlebags. No regrets buying these pipes.

 Raithius Posted:

Love it!! Sounds great, noticable power increase. Easy to install and packaging/delivery was prompt and secure.

Important Product Notes

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.

• Flanges and retaining rings are not included with most aftermarket exhaust for 1984-2013 Evolution and Twin Cam models. Re-use your existing hardware, or purchase replacement hardware.
