Full Exhaust Options

I've been talking to a few exhaust manufacturers, gathering information regarding full systems for the GSX-S since info seems to be scarce at the moment. I will try to condense it for all the members that are considering getting a full system (because as most of us know, a slip-on isn't gonna do jack ****).

Here's what I've got so far:

Arrow

Note: Select worldwide on the ebay sidebar to see all of the options. Some are free shipping.

Headers/midpipe only - $713 to $740 (ebay) - replaces stock headers and midpipe. Keeps O2 sensor bung. Can be used with stock end can (very loud) or theoretically with any aftermarket slip on that fits the stock midpipe. 4-2-1 design.

Full System - $867 to $1000+ (ebay) - several options for the end can including shapes and colors. I saw one user on this forum that had fitment issues between the can and midpipe (too loose). Includes removable baffle.

Weight: 4.34 KG headers + 2.17 KG can
Rear wheel gains: +5.6 HP peak. +~10 Nm midrange (torque dip completely gone).


M4

Full system - $857 (sportbike track gear or ebay) - black can tucked under the footpeg for a more compact look. Built-in bungs for o2 and wideband sensors. 4-2-1 design. Removable baffle.

Weight: 12 lbs total
Rear wheel gains: +8.3 HP peak. +~8 Nm midrange (torque dip almost gone).


Yoshimura

R11 Full system - $1141 - $1250 (contact [email protected]) - clean system with 4 color options and a higher profile can up by the passenger footpeg. 4-1 design. Removable baffle. Ships from Japan (up to 2 weeks) but you only pay local shipping from CA.

Weight: 6.1 - 6.3 KG
Gains: +~2 hp peak. +~8 Nm midrange (torque dip still exists but it's much improved).


CS Racing

Full system - $715 (ebay) - TaylorMade style, has a small muffler box where the stock one is so it is possibly not as loud as the other systems which tend to be straight-through. 4-2-1 design. Removable baffle.

Weight: 6.3 KG
Gains: +4.7 hp peak. +~5 Nm midrange (torque dip still there).


Others

Akrapovic told me that they do not plan on making a full system for our bikes. I am waiting to hear back from Remus.

See the attached dyno graphs for each exhaust system. These were all supplied directly to me by the manufacturers except the M4 one, which I found on the forum (still supplied by M4). Keep in mind that they all use different scaling, units, etc. so it is not advised to compare them directly. For example, CS's graph is tall and narrow so it makes the torque dip look a lot worse than Arrow's which is short and wide.

I like the Arrow flattens out the torque powerband. Too bad about Akra not making one.

Yeah, that would be killer for roll-ons. Imaging getting more torque instead of less as you go from 5k rpm to 7k.

In addition, the Arrow rep said that the supplied dyno was done with no other mods at all. So with a fuel controller or ECU tune it will be even better.

I also asked Akrapovic the same a couple months ago, (akrapovic Benelux) (Belgium, Netherlands, Luxembourg).
The same answer, no plans for a full system in the near future.

Thats when I decides to pick the Arrow headers with a custom akra can with a PC-V
Headers arrived yesterday, also the exhaust valve eliminator.
I'm waiting now for the new gaskets (orderd already) to make an appointment with the exhaust builder.

Missing a colon in your link (http// vs http://).

That's pretty cheap! Seems pretty loud, though. I'm eager to see a dyno graph.

Some updates.

Leo Vince, Remus, and Jardine have no plans for a full system.

Two Brothers is "working on something" and will have more info in 4-6 weeks.

Motad has a full system, and it's cheap, but they haven't replied to my emails asking for info.
