These are a Noxious Customs flagship! The Noxious Customs "Stockie" header gives you the option of retaining your stock running gear and giving you the option of true dual exhaust!
Built to fit into the most stock type applications for your 303, 324 and even some 371 Oldsmobile built engines. We even have a model to accomodate a stock generator!
These are made for Hot Rodders and customizers who need a center dump style block hugger header for their 303, 324 or 371 Oldsmobile built engines. These are not a header that will work in any stock-type application.
Noxious Customs Shortie headers hug the block nicely and fit inside most frame rails with ease.
These babies are short! Designed to be problem solver headers and not for stock applications, these will fit the 330, 350-455 Oldsmobile built engines. These are great for street rods, hot rods and many other custom applications!
The Noxious Customs Stubbie header hugs the block tightly and is extremely short, fitting even the most extreme cases.
