Fantastic service and product.

I wouldn’t hesitate to use Bills Exhausts again, first class service from the moment I placed my order, constantly updating the progress of my shipment all the way to the UK. The light itself is amazing, fantastic quality, design and performance. I couldn’t be happier.

Excellent product

I needed to upgrade my stock fender and didn’t want to cut wires and this product was easy to install and you use the factory license plate light without cutting wires. The installation was very easy to me. The customer service is great and also the shipping was very fast which I was impressed and definitely ordering all my parts from Bills Exhaust.

Excellent Air Filter

This is the real deal, not the Chinese knockoff garbage that falls apart on Amazon. The foam is denser and much more ridged than the knockoff. Comes with a new clamp too.

Easy, Like it should be!

I purchased some exhaust parts from Bills Exhaust and had a great experience. Bill kept me up to speed with order progress and reached out when he knew one of the euro parts would take a bit longer to get. It's everything you want in an exhaust supplier and none of the things you don't want! I'd definitely buy more stuff from Bill!

BEST WEBSITE TO BUY FROM

The customer service was outstanding and the packaging was padded extra to make sure my full system came in undamaged. They contacted me personally about difficulties with my order and did what they had to so it could be delivered to me and went out of their way to send it personally with next day shipping. All my boys I ride with will come to Bills Exhaust for their systems and I will never go anywhere else for my future bikes. Best spot in the nation.

Vandemon 4-2-4 system for z900rs

Great system. Unfortunately there are no instructions whatsoever. I assumed that a clip went between the left passenger foot bracket and ended up breaking a $100 foot bracket on my motorcycle. Couldn’t believe it!!! How hard would have it been to just put a simple drawing in with the exhaust system to at least picture how it needed to be assembled. Hopefully JB Weld will glue this back together. :-(
On a brighter note, BILL’S EXHAUST STORE is absolutely awesome!!! Super customer service and Bill was really nice and kept me updated on my order the entire time. Highly recommend!!! Thank you Bill !

Springs are finished / polished well, and are marked with spring rate on the end which is nice. Looks like a high quality spring set.
