excellent product quick delivery great sound and better performance

 Wolfs MC Repairs Posted:

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! :)

 bozzz99 Posted:

great

 rpejsa 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.

 chris_lacey Posted:

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

 chris_lacey Posted:

Great system. The sound alone is worth every penny

 jerpat1964@live.com 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

 AZRprman Posted:

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

 dansflhr Posted:

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

 ABChamber 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!

 north ferry choppers Posted:

great pipe makes alot of power

 JDAVIS1113 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

 asmcdennis Posted:

Nothing like the sound of a Thunderheader

 flhtrider Posted:

Installed on a 1989FLHTC. Good instructions, good hardware and good fitment of the details. The sound is authentic.

 mlbean Posted:

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

 jeffrey98837 Posted:

Awesome sound. Looks great on bike.

 jeffrey98837 Posted:

Greta Sound!!! Love these pipes!

 hjriedel Posted:

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

 syamsulfaiz 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.

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.
