Frequently asked questions
How much HP do headers add to a 5.7 Hemi?
With the larger 1 3/4" Hooker BlackHeart headers (p/n 70102303-RHKR), the "cam'd" 5.7L Hemi produced 442 horsepower at 6,100 rpm and 437 lb-ft of torque at 4,500 rpm. This represents a gain of 35 horsepower over the stock manifolds with the larger, long-tube headers.
Which is better, exhaust manifolds or headers?
Headers typically reduce exhaust back pressure, boosting performance at higher revs and resulting in increased noise. On the other hand, exhaust manifolds maintain some back pressure, which ensures drivability across a wider rev range and reduces noise.
Do headers affect exhaust sound?
With exhaust headers, your exhaust notes will be smoother, more defined and far more aggressive.
Is it worth upgrading headers?
Headers can increase horsepower, improve the flow rate of exhaust or improve your car's sound. No matter what you're looking for to enhance your engine system, you can find an exhaust header to suit your needs.
