Crush bent horsepower loss
Just curious how big of a deal crush bent exhaust really effects a setup. I am in the 800hp range and would like an opinion on my current exhaust setup. I have supplied a pic of the largest restriction. Am I leaving power on the table ?
1-7/8 headers, xpipe, 3" spintech mufflers, sweet thunder resonators. Full 3" crush bent exhaust

Keep in mind that test was 500 Hp and through a short extension with no muffler. Not 800 and through a full exhaust.
IMO it is affecting you.
The real question though is how much? 5 HP, 10 HP, 15 HP ? If it's that small of an affect, Is it worth spending the money to re do it?

Lol, that guy is really making a name for himself for being a being a fng idiot.
OP, sure those bends are costing you. Again, who knows how much. How many bends do you have? Would it be possible to replace some? Buy some mandrel bends and have them welded in rather than redo the whole exhaust?

If the system didn't have a crossover in it then I would say it's costing you some power over a mandrel bend but with a crossover I can't see it costing you much if anything. If it's a street car you won't notice the difference at all, If it's a drag car you wouldn't want any exhaust anyway.
