Don't be hating because nobody buy your JDM license plate homeslice. How many of those "numerous cylinders" you bolted on still last? Those welded cylinders can withstand a constant 40psi all day. There's no such thing as overkill when you could have peace of mind. You don't want your manifold to go kaaboom and comes off like in Fast and Furious. You got to pay to play son!
