The price was right, the sound is awsome......great experience. Thanks again J&P!

  Posted:

Best!!! not my first set The sound and the most of all the Performance I have tried many others and have worked in a bike shop this is the best slip on out there

  Posted:

i have the thunder header 2 into 1 on my 02 flhtci with a procharger blower and i bought the true duals for my road glide because i like the performance and sound of the thunder header. its the best for both applications.

  Posted:

Didn't like the sound of my stock muffler. Too quiet. I want people to know I'm around and this muffler took care of that.

  Posted:

Excellent fix

  Posted:

They fit and sound great. No problems on installation. Not as flashy as some, but you can't duplicat that Thunderheader sound.

  Posted:

awesome

  Posted:

Exactly the tone and just the right amount of bark to let the cagers know your there. Great look and fit on the S/G. bagger

  Posted:

THEY FIT NICE , HAVE A NICE RUMBLE , BUT WHEN YOU OPEN THE THROTTLE THEY COME ALIVE . NOT AS DEEP AS 2 INTO 1 T HEADER BUT THEY LOOK GOOD ON A DRESSER WITH TRUE DUALS

  Posted:

Great sound for right now, but will be MUCH better once I can get the headers changed and tune fuel control.

  Posted:

Love the mufflers. Sound is deep and loud just like I wanted!

  Posted:

Outstanding sound and performance. More than I expected

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.
