So true Steve, and we hear the same - " an exhaust can't make power "
But yes it can, ant when the TDC lift goes up the difference from a very bad to a very good exhaust concept is so huge.
Primary to secondary length / diameter - collector design and reflector to absorber.
It can make an engine alife or kill his good spirit.
Best reg.
