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
Doubt it's costing you anything. This video covers headers but I think it will make you feel better about your exhaust in general.
Very interesting results to say the least.
Yep...I was actually just adjusting my sig to show who the OP is.
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?

The pic shown is the worst restriction, from the floor board up over the axle and into the center exhaust tips. rest of it is pretty straight shot.
It's not necessarily the reduction in tube size that effects performance. The dents and ripples in the pipe can cause turbulence and areas of slight flow reversal.
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.
Wow, insane with the header bashing... I would have guessed it would have hurt it worse. Might as well just remove your cats on your stock manifolds and run them... LoL
Was wanting to know how much of a reduction in diameter , from pipe bender machine in a exhaust shop like OP has done. Anyone have a idea of measurement ?
