Is it generally agreed upon that short pipes reduce bottom end power? Is it a lack of back pressure or something else entirely?

I see old TT racers with pipes exiting just under the engine, but if it reduces low end power, what is the greater advantage gained on course that has a lot of acceleration out of tighter turns?

The bikes are sideways,with tires spinning.They keep the R's up that way.Just as in all forms of racing,gear ratio,head and camshaft configuration are the biggest part.Take drag racing for example:

Guy X has a small block 3500lb. Chevelle that spins 8000RPM with 4:56 gears

Guy Y has a big block 3800 Skylark that spins to 6000 with 3:73 gears

They both run 11.90's


All in the combo.Run those TT pipes on your Trump if you want.They do look good on the right ride and they are LOUD.I run drag pipes on my BSA and think I may run a baffle in them.It's kinda loud and you could never have enough bottom end.
