Iím familiar with scavenging, just wondering why so many go aftermarket if this significantly reduces low end...
Then you missed my whole point  :157:

You can't compare a hacked OEM exhaust with an aftermarket full exhaust.

I had a Honda magna 83 that I perced the end of the original slip on. Total disappointment on the first ride I noticed the power lost even on this kind of bike. Sound was nasty weird haha

But thatís my specialty!

I figured this is the case... So in other words slip ons basically do nothing but decrease performance

Again, just to clarify for anyone reading this and wondering about these mods. Ditching the CAT (the real cat not the breadbox) will most certainly gain performance. I had a noticeable increase in the whole rev range. It was going to either a slip on or no 2nd muffler that seemed hurt low and mids

Depends on the slip on.

Tighten it 'til it strips then back it off half a turn.

thats odd.... all the manufactures promotes an increase, but dyno says the opposite.....  :112:

Some are quieter than stock too!
The manufacturers know that the dB killer will be removed the real world.

I bought hand made headers for my z900 one year ago. Combined with akrapovic silencer (with dbkiller) the loss of torque at low rpm is really noticeable. The sound is incredible: clean, nice and not so loud not so silent, perfect. The problem is the lack of torque at low rpm.

I really miss how good did work the bike at low rpm when I had stock headers installed, but I hate the stock sound.

I don't know if akrapovic headers would solve this lack of torque at low rpm. The problem is they are so expensive.

Right now I swap between original headers and handmade headers every 6 months so I can enjoy the best of both but I would like to find a final solution. Not sure if there is one.

Hand made?
Sounds interesting.  :084:
It may be unfair to say that all headers will loose low end.
Pipe lengths and diameters will have a big influence on how power is delivered.  :169:
Does the guy who made your headers have a lot of experience?
Any pics?  :018:
