There was rust on one of the mufflers and they took longer than the catalytic converters to arrive. At the exhaust shop, I was only allowed to install one set because of some law that prohibits moving to dual exhaust. I've got to look into this law and find another exhaust shop to install the second set

Easy and simple.

I ask Edwin a question or two about my Application and how to in install and he return quite quickly!

Very easy

Great job!

All Good

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.<br><br>Best prices around.

I do not want to share my Amazon information!

Easy to use website and fast transaction and shipping.<br>Really great

Great service. Shipped out the day after I ordered it...plus it was the cheapest of the competition.

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.

Cheap prices, great quality, and fast delivery. Autoplicity will continue to receive my patronage.

Easy and fast. Order arrived very fast. Thanks.
