found what I need at the price I want to pay. there is not a lot of details on what you are buying. I found I had to check with other sites to insure I was buying what I wanted. also postponed buying brakes becuase of this.

Great prices. Fast Shipping. I would definitely do business again.

I ordered online with autoplicity via google checkout. It was easy and a real good price compared to other sites. The communication was great every step of the way. Order confirmation, order tracking number and shipping number. Super fast shipping for a heavy item (springs)and was in perfect condition. I Will shop with them again.

Hands down the best price on the Magnaflow catback I have seen by more than 20%. They were able to work out the ship-from-manufacturer tracking after a quick phone call. Will definately be recommending these guys to others.

awesome price and super fast shipping. I will use again. Thanks
