Question about Torque Chamber - April 30, 2013, 02:35 PM

Ok, So Im about to buy a full exhaust system for my 09 GSXR 750. Guy is selling the exhaust and said it had torque chamber, and was spring loaded.

Sorry for the noob question, but what exactly is a torque chamber? Looked online, and it seems its sort of like a baffle but not really? What does it do, whats the exact technology behind this.

This is for a streetbike. It enhances low-midrange power. You will find it on stock pipes. (I haven't heard that any aftermarket pipe has one, but you never know.)

Essentially it narrows the exhaust pipe, giving you more low end torque. Looks at a stock exhaust header versus a race header. The pipes coming out of the engine on the race header are larger. That means the power is made high up in the RPM's.

Soooo. If you put a race header on a typical streetbike, it loses some of the rideability. Low end power (which is what you use around town typically) suffers. High end power is better. (So if you are on a racetrack, do you really care if you don't have any power below 5000 RPM? Probably not.)

Got it?
