How much are headers and exhaust systems worth on the dyno, or in the car? The numbers might surprise you. But what’s funny to me is how some exhaust mods impact different combos. After all, we all know that on Engine Masters we saw Freiburger and Brule “dimple” header primary tubes an insane amount without effective horsepower. But that all depends on the combo right?
Well in this video from Richard Holdener you’ll see all kinds of exhaust and header tests to see just what they do to overall power. Check it out.
Video Description:
DO CHEAP LONG TUBE HEADERS REALLY WORK? HOW MUCH POWER ARE SHORTY HEADERS REALLY WORTH OVER STOCK MANIFOLDS? HOW MUCH LESS POWER DOES A COMPLETE 2.5-INCH CAT-BACK EXHAUST SYSTEM MAKE THAN AN OPEN HEADER WITH COLLECTOR EXTENSIONS? WHAT SIZE EXHAUST WORKS BEST ON A 900-HP TURBO 6.0L? CHECK OUT THIS VIDEO WHERE I TESTED THE DIFFERENCE BETWEEN STOCK EXHAUST MANIFOLDS, SHORTY HEADERS, CHEAP LONG TUBES AND EXPENSIVE LONG TUBES ON BOTH A STOCK AND THEN MODIFIED 4.8L! THE VIDEO ALSO COVERS THE COMPARISON BETWEEN OUR OPEN DYNO EXHAUST (LONG-TUBE HEADERS FEEDING 18-INCH COLLECTOR EXTENSIONS) AND A FULL 2.5-INCH X-PIPE EXHAUST WITH MUFFLERS AND TAIL PIPES. LOTS OF EXHAUST TESTS HERE-MAKES URE TO CHECK OUT richardholdenerperformance.com FOR GREAT DEALS ON LS CAMS, SPRINGS, INJECTORS AND LIFTERS.
