Great sound and looks!

Perfect fit, exactly what I wanted performance wise

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

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.

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.

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.

Good exhaust

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.
