The portly stock mufflers distract from the otherwise tidy lines of the bike.
According to a recent SSB
poll, an aftermarket slip-on exhaust system is the first mod most riders purchase. More important than a fender eliminator, smoked screen or flushmounts, an aftermarket pipe is widely regarded (even beyond our online poll) as a must-do mod.
Whether it’s some sound you’re after or maybe more power and less weight, if you’re in search of serious bang for your buck, a proper slip-on goes a long way in bettering your bike.

Remove the two mounting bolts and the mufflers are gone.
Take for instance our 2009 Suzuki GSX-R1000. Although newer bikes have snatched its limelight, one street ride on the big Gixxer and you’ll wonder why anyone would want anything else. It handles like it’s on rails, has strong midrange shove with an explosive top-end and it looks great—save for the stock mufflers. But thankfully we found an easy fix and while the dual pipes add some balance to the stock bike, there was no sense spending nearly $1000 on a pair of slip-ons when Two Brothers offered a nice single system with a catalytic converter delete (sorry Prius drivers, the horsepower made us do it).
Two Bros Racing offers single-canned systems starting at $469 that can be installed in roughly 30 minutes with basic hand tools. In our case we opted for the new Black Series titanium can to match the midnight scheme of our GSX-R1K.

A few more bolts and a little wiggling frees the cat from the header.
On the scales the stock slip-ons, catalytic converter and all associated hardware weighted a hefty 21.3 pounds, but our Two Bros system only tipped the scales a mere 5.8 pounds for a total weight savings of 15.5 pounds.
The install was a breeze and after the smoke cleared on the dyno we were left with gains of 4-5 HP in the midrange and a 2.5 HP bump at peak. As for sound quality, it’s second to none with a deep, raspy tone. For the sound conscious communities you can always spring for one of the available quiet inserts.

The exhaust matches so well it's almost as if it was custom made for the GSX-R1000.

Solid gains of 4-5 HP in the midrange lead way to a 2.5 HP bump at peak. Not bad when you consider it also shaved 15 pounds.
The weight savings and additional power are nice, but the pleasure the pipe adds to the riding experience is priceless. Pops and snarls on the overrev provoke thoughts of MotoGP bikes at the track and a quick rip up an onramp brings a smile to your face–a nice exhaust has a funny way of bringing out the inner kid. And in this day and age, if a mod helps put a grin on your face, it’s money well spent. ssb
