Since when is backpressure good for top end horsepower?
well the loss in back pressure is the only thing i can think of. Cuz once i did the pipe it lost some speed. 129 yes
We're talking about a lightning or a firebolt, right? If so, a 20 hp gain is not possible from an exhaust and filter change. With a custom tune, FAST air intake, and an exhaust, I didn't even come close.

so the jardine is weightless and lightens other parts tooshaved 25 pounds off my bike by going to a Jardine titanium pipe
Is he talking about an 1125 maybE? Or maybe by some Weird chance they modified his Internals with a big bore kit, race cams, etc.
I have a jardine, open airbox and mine feels like every other firebolt I've ever been on. No 25 horse difference
ok this thread went to crap. i was actually interested in some REAL feed back on the subject since i need a new ecm and might not get it til winter so i was thinkin of doin the breather and air box mod so i prolly need different mapping/
The REAL feedback is all over this board. The REAL feedback is that if you're doing an exhaust and an airbox mod, you should change fueling. The REAL feedback is that you can flash a race map, buy an EBR ECM, custom tune yourself, or book my services to do it for you. The REAL feedback is that a simple search will turn up all the other REAL feedback.
I don't mean to be a dick about it, but this isn't your thread, you don't get to judge how people respond to outlandish claims, and the answers to all of your questions so far are readily available in a number of different locations.
K guys yes 129 horse. It is a lightning. The engine mode are as followed. Race map, custom pipe similar to race pipe, open air box, and cams. I didnt mean to stat any arguements. But it is possible
