Love my TTI headers on my 440! I bought a set of headers from Stainless Works and had nothing but PROBLEMS! One tube was out exactly an inch. When I called to get corrected I'm told there must be something wrong with my car. Was given several bogus reasons. Finally I returned them (at my cost) to prove they were wrong. They responded saying they were fine but did me a favor and "adjusted them". Since when is a tube out by a full inch an adjustment? George the sales manager said he would refund the shipping but never did and won't even return a call. Lousy service, not worth the high $$$$$, took forever to get and then took forever to get fixed. Just because their name was in a magazine does not make them a reputable business.
