mfg Posted February 28, 2023 Report Posted February 28, 2023 L&R rear exhaust pipes (pipes ahead of mufflers) connected with a crossover pipe (as factory installed on some Studebaker Avantis) add horsepower......True?
Gunslinger Posted February 28, 2023 Report Posted February 28, 2023 A crossover balances out the combustion impulses between the two cylinder banks and increases power and does change the exhaust tone. I’ve read that tests show an “X” crossover is more effective than an “H” type crossover in producing more power.
