  Posted:

Wow what a difference a thunder header made on my 01 dyna... It plus theRSD judge Venturi air cleaner awoke my sled right up... Thanks J&P Cycles

I have a Thunderheader on my '88 FXSTC, along with other modifications, and had it dynoed at the local HD Dealership. It dynoed real sweet. I have a '00 FLSTC which I am ready for a new exhaust system. I will go with a Thunderheader! I have tried multiple exhaust systems, and this system seems to do the best for performance (in my opinion). Wolf

Love the Thunder Header! :)

  Posted:

great

  Posted:

Had to replace my Thunderheader when it just plain turned to dust. (It was very old) The only choice was another Thunderheader. I run a EV-27 and E carb with this pipe and everyone thinks I have installed a big bore kit. This header really works.

  Posted:

Great sound and performance. Fit and finish is a little rough, definately not show quality. Good for street use

  Posted:

Great system. The sound alone is worth every penny

  Posted:

I just had the motor on my '97 Harley rebuilt. The Thunderheader 2into1 was recommended by my friend that did the work. I replaced the Vance and Hines longshots I had on the bike. So far, I'm extremely happy with the performance and sound. I'm just finishing up on the 500 mile breakin period. They look awesome on my "new" Harley. Thanks....Jerry

awesome. my '92 dresser never sounded better than this.

  Posted:

My thunderheaders make my bike run smoother, doesn't pop anymore, and has more power.

  Posted:

I like the sound a lot. My hubby used to have T-headers on his bike - I miss the sound of it - until now!

  Posted:

great pipe makes alot of power

  Posted:

I have the 2 into 1 on my 06 Street Glide! I love the way it sounds, and it's just got the low end torque that makes you wanna keep on that roll! You won't be disappointed! Invest

  Posted:

Nothing like the sound of a Thunderheader

  Posted:

I love the sound and increase in horsepower. Both my bikes have Thunderheaders. I will never buy any thing else.

  Posted:

Awesome sound. Looks great on bike.

  Posted:

Greta Sound!!! Love these pipes!

  Posted:

Added a good amount of power. Looks and sounds great. Perfect pipe for my superglide.

  Posted:

The best exhaust for Dyna in term of performance, sound and value for money. A must have for outlaw-style dyna, if you know what I mean.

Best Bolt On Header For More HP&Sound,Out There -Thank You Thunderheader,J&P-Very Very Happy! Makes Riding The Bike More Fun! I Got Five-CRAGAR"

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.
