very good price fast shipping

Item arrived quickly and as described. Thanks

Found Autoplicity by doing Google search looking for Corsa Sport Axle Back exhaust for my 2008 GT500. By far the best price, even cheaper than other big companies with free shipping by far. Ordered them on Thursday afternoon and got them 24 hours later in NY with the standard shipping. Could'nt be happier.

fast, polite service when we had a question
