i think delkevic deserve a mention on here.
i ordered my silencers by phone.
i was told they would be delivered the next day.
sure enough they arrived the next day.
was also told of progress via text on each step of the delivery, order confirmation, posted, and letting me know when the parcel man was coming to bring my prezzy.
completley hassle free, cheap after market exhausts, great customer service.
i would recommend these guys, plus cheaper direct, rather than on ebay.
