What are the pros and cons of long tube headers vs. short tube headers? I realize the long tube headers push the cats back, which requires purchasing either state threw down pipes or high flow cats, and neither are street legal, but my question is focused on hp and torque.
I have read reviews saying long tubes are better, and have found things like short tubes are more for low end torque, but I haven't found many dyno sheets showing before and after with short tube vs. long tube.
In a recent Mopar magazine they installed short tube headers on a Challenger R/T 5.7L and it looked like with the dyno results 8-9hp at all rpm ranges. Is this typical?
When people say "long tubes dude", "Go with long tubes, you wont be sorry", "Long tubes are the best", "My long tubes are great", "Just do the long tubes you wont be sorry", or "Long tubes make more power" is it because they also need to go with high flow cats or no cats at all that they are seeing additional 10-15hp so the package is so much better?
So when I read short tube headers are better for low end torque, then I see even 8-9hp across all rpm ranges that makes me think long tube headers have less hp at low rpm. So does the long tube headers make about 5hp in the low rpm, then 10 in the middle rpm, and 15 hp in the high rpm to redline? So they do make more max power, but less low end?
If one put high flow cats on a short tube header and each provided about 9hp, for a total of 18, would that be close to what a long tube package provide?
