SHIPPING FOR SUCH A SMALL ITEM IS MORE THAN THE ITEM ITSELF, THATS JUST WRONG!

Relatively easy. We'll see how fast and simple shipping and delivery ends up being.

Went great thanks

cheapest price, multiple payment options, shipped very quickly overall good experience

I searched around and Autoplicity had the best deal. their website was easy to navigate and checkout, and the order shipped quickly. I would definitely buy from them again.

Excellent communication, quick, easy, and lowest price.

The price was right and the product was shipped quickly and arrived early. I would recommend them to my friends and family and will order from here again.

I searched and searched and could not find a good price then i found Autoplicity and gave it a try, i couldn't believe i found my headers i wanted at an incredible low price, let alone the shipping was at a fair price even total price was lower than ebay or other places, definitely keeping this site on my sights for new parts and other products im keeping in mind!

Customer Service was excellent. Their online website provided accurate product description and when I called to double check, the gentlemen handled my request with ease and professionalism. Thank you for providing the best pricing on great automotive products. My wife and I purchased a WeatherTech trunk liner that would have cost me over $100 retail price but was able to purchase from Autoplicity for much less!!! Thanks guys and keep up the good work!!

This caliper paint green and cool.

They had the best price on the internet! Fast shipping and repsonse.
