Great sound and looks!

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.

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

great quailty exhaust, install a little hard due to needing to drain transmission in order to install mounting bracket.

Sounds great and gained some power

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

I purchased the Thunderheader to replace my V&H Short Shots. Immediately after install, there was a noticeable power difference. The responsiveness was awesome and the sound is a deep, throaty bass! It sounds like a monster and I highly recommend the product.

Awesome pipes! Sounds mean and has a great look when you wrap them!

Love it! Sounds great on my 2010 wide glide

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!

Best fit for my bike and sounds great!

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).

Great exhaust, great sound but a bitch to put in. I had to install it twice as the 1st time I pinched an exhaust gasket trying to get the head pipe into the exhaust flange. Then scratched it putting it in the second time...

This exhaust is great! The only complaint I have is that they didn't come with heat shields. And when installing make sure to get the right seals. I needed the screaming eagle seals for my 17 Low rider S

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.
