I have an S4Rs with boomtubes installed, and I don't think the bike feels quite as quick as it did with the previous full aftermarket system I had installed. 

It's not so much that I need the extra power, but I had gone to the effort of getting my ECU remapped and opened the airbox, and I'm curious how much power the boomtubes may sacrifice compared to a performance oriented full system like Termis, Arrow or Remus.  To be honest, they look so good I'm likely going to stick with them, but some actual data would help make the decision.

My understanding is that boomtubes DO sacrifice some power versus quality full exhaust systems.  My question is, roughly how much power might I be losing for a bike like mine with the aforementioned mods?

Thanks for any info.

I had always wondered if torque cones would help the boomtubes. they help the shorty exhausts on HDs

~10 hp (give or take) from what i have read/been told. 

kicking around doing the same thing with the same bike. 

A search will tell you that you'll lose a few ponies on the top end, but does it really matter?  If you want a lot of horsepower, you own the wrong bike.

P.S. I've been running boom tubes for a few years, and I have no complaints about power loss.

I established that I knew there were some ponies lost.  I established that it really didn't matter, but I was curious about specifics.

My search turned up no meaningful data, just vague impressions similar to mine.  If you have some actual data, posting that would be helpful. 

I think most people would agree that 130ish horsepower for a motorcycle, though subjective, would generally be considered "a lot". 

Your lack of complaint about power loss isn't particularly relevant to what I was asking.

The only numbers I've seen are in this thread.
