HEADER FITMENT • Our headers were designed to fit with the engines located to the factory specifications.  If the engine is not located correctly in the chassis, the headers will not fit properly.  We strongly suggest you check your engine location prior to installation.  (Click here for the factory dimensions) • Due to various manufacturing designs, aftermarket parts, engine configurations, suspension combinations, etc... TTi cannot ensure headers and exhaust systems to fit all combinations.  However, we have done our best to accommodate both factory and aftermarket component combinations.  In some cases, slight modification or repositioning may be required on your part to clear the specific situation.
