Great sound and looks!

  Posted:

One of my best purchases. Thunder header was my first choice from a performance point. And the price was right.

  Posted:

I have been running this ThunderHeader for roughly ten thousand miles so far. It looks great, sounds great, improves performance compared to other pipes I've run from idle to wide open. The only issue I see is the finish cause a week after I installed the pipe I noticed surface rust over pretty much the entire pipe. Tried ceramic high temp paint but that didn't work so I have a feeling this beautiful pipe is going to be hidden behind some header wrap before to long.

  Posted:

Great header! I'd say the best! Looks as good as it sounds too

  Posted:

Runs great on my '99 electa glide. Not as loud as I had hoped and it was built up to be, but still a great performing system! In hindsight, I would have purchased Chrome instead though.

Bought these pipes on scrach and dent, BEST pipes I ever had! 91 FLHS wood W6 cam

  Posted:

Purchased for my 99 Electra Glide and about a year later I'm ready for something different. The pipes installed easy enough (though you have to remove the tranny cover to install a new bracket). But the black version has had terrible color fading and honestly, this system has never quite produced the sound i'm looking for. The horsepower is fine, but I really want a beefy throaty sound. This system is more middle-of-the-road as far as sound goes. Only real downside is the black fading. I'll stick with Chrome from here on out.

  Posted:

Thunderheaders produce extra power, without question, and they sound great. The big downside to the black pipes is the finish...it's horrible and I strongly recommend powder-coating or repainting (with VHT) prior to installation. Discoloration is only part of the issue, a bigger part is the rust that comes from shoddy paint. Heat shield may hide it, but they don't stop the rust, and that will quicly lead to blown out pipes. I have another bike with these pipes and they've been powder-coated, and they're many years old with no problem.

Perfect fit, exactly what I wanted performance wise

  Posted:

Fantastic product at a realistic price as long as you are a gold member & I am .

  Posted:

fit like it should , still had to modified the front foot mount to clear pipe!

  Posted:

Exhaust quality is good. Install was easy. Instructions are ok. The coating on the pipes is very cheap though. Easily scratches. For the price of the Thunderheader, I expected to have at least a high temp powder coated finish or ceramic.

  Posted:

Unmatched torque. Perfectly engineered without the hassle of changing out discs. Sounds and looks amazing. Price is fantastic. All in all best pipes available.

  Posted:

Nice pipes

  Posted:

The best $593.99 I've spent on my 08 SG. It was well worth the wait.

  Posted:

Great product! Noticeable change in performance. The black pipe looks great on my "08" Street Glide. Looks better without the shields but the heat may end up being an issue so I may end up installing heat shields.

  Posted:

Thunder headers give good power off the start. Good sound. Black finish you will need to wrap or get black heat sheields as the color turns brownish when it gets hot. It will get HOT it also picks up road grime amd discolors. Still over all like the pipes!

  Posted:

First, I'm a fan of the sound. I don't want that super loud drag pipes, but I want to be heard. These don't disappoint there.

  Posted:

Great product. Was so pleased with the exhaust I purchased for my Dyna that I had to buy some for my Street Glide! Nothing sounds like a Thunderheader.

  Posted:

product is not gloss black, good match to my black denim paint. if you have a 88 or 96 inch motor this is what you need.

  Posted:

now my bike sounds like a Harley!

These thunderheaders were just whatbi wanted. Deep, loud, thunderheader sound. I put them on a 13 road glide and install took less than 2 hours. Wouldn't change them for anything else. If you want to be heard, and have a good looking exhaust and added performanceget them and dont look back.

  Posted:

Good exhaust

  Posted:

Excellent piece of equipment. A vast improvement in the sound of my ride and no more burned legs for my passenger on that top pipe!

  Posted:

Best fit for my bike and sounds great!

  Posted:

I absolutely love these pipes. They look great and my god do they sound good. Take note that if you are on the 103 that these pipes will be VERY hot. Not that other engines do not get hot but I have used these pipes on other engines and they didn’t throw off nearly as much heat. I would recommend getting the heat shields (sold separately).

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.
