ron cooks garage is a local favorite because their work is professional I have had them do custom exhaust work and the work was not only excellent but the pipe they use went through a winter on my truck without one spot of rust. now to some people teir prices may be steep but you generally get what you pay for not always but at cooks quality costs but its worth it in the long run so you can spend less for a cob job and poor quality materials or you can spend the bread and get ahead.
