Everyone always tells the newbie poster to search instead of giving an answer to what exhausts are out there for the second generation SV650. And to be honest, the search engine sucks here. So, hopefully this post will put a stop to both the Exhaust threads and the bunk replies to 'em.

First off, a bit of information:

Exhaust Fitting

The '03 SV650 is unique, as it's the only year with the more elevated subframe. Exhausts made for an '03 will not fit '04 and newer bikes. Exhausts made for '04 and newer bikes will not fit the '03. If you have an '03 SV650, make sure the exhaust is made for the '03.

If your bike is an '04-'06, any exhaust made for any of those years will fit your particular year of SV.

**Note**If you have a 2007 SV650, your bike also has an O2 sensor. Full systems made for previous years will need have a bung added for your O2 sensor to fit. I'm not sure about slip-on fitting, that's still to be determined.


Exhaust Types
There are two types of exhaust systems for your SV. You can purchase a slip-on exhaust (generally less expensive) or a full system exhaust (more expensive, but it nets a bit more power).

Slip-on Exhausts

• Less expensive
• Easy to install
• Reduced weight
• Doesn't require a remap*
• Requires modification to stock exhaust system

A slip-on is generally less expensive and easy to install. To install the exhaust, you will have to cut your mid-pipe (using a hacksaw, sawzall/reciprocating saw, angle grinder, plasma torch, jaws-of-life if you're nimble, you get the picture...). It's a very easy procedure to do and requires minimal tools. Slip-ons will give you a louder and deeper sound to your bike and a nice look, but rarely do they net a power increase, and if they do, you won't be able to tell. In general, a slip-on will not require you to remap your bike's fuel injection mapping. This modification is best suited for street riders.

Full System Exhaust

• More expensive
• Reduced Weight
• Generally nets a HP/Torque Increase
• Does not require modification of stock exhaust system
• Will most likely require a remap*

Full system exhausts replace not just the muffler, but also the the mid-pipe and exhaust headers. The result of this is far less exhaust system weight, a HP/Torque gain, and an open and deep exhaust tone. In general, full system exhausts will require a remap of the fuel injection mapping. A high flow air filter should also be installed. This modification is best suited for track day addicts and racers.

High Mount Vs Low Mount

It mostly comes down to a cosmetics battle, but each setup does have it's advantages and disadvantages. A high-mount muffler generally offers better crash protection (it's less likely to get damaged in a low side/high side) and may offer improved aerodynamics (the SV tops out at 130 mph, so it's not really gonna make a difference). However, a high mount can's mounting position makes mounting saddle bags almost impossible. Also, a high mount can is generally a bit more expensive because the mid-pipe must be bent at more extreme angles.

Some have reported that their high-mount can's mid-pipe interferes with their right side foot position on occasion. To remedy the problem, they have made heat shields for the mid-pipe to prevent the pipe from melting the heal of their boot.

There is some debate as to whether or not a low-mount setup flows exhaust gases more efficiently than a high-mount set can. In theory, the extra bends could restrict airflow to a degree. If you take time to look at your exhaust system, however, you'll notice far more extreme bends in the headers and exhaust collector that can be more major constrictors of exhaust flow. As long as I've been a member here, I've never seen proof of a low-mount can's exhaust flow advantage. Even if it did have an advantage, the amount is miniscule - it would net a fraction of a horsepower at best.

* Fuel injection mapping - Because of the primitive nature of the SV650's fuel injection, the engine is not able to cope with increased airflow through the engine - in other words, the bike will generally run lean. A lean condition can cause damage to your engine over time. Remapping the stock fuel injection will generally increase fuel delivery throughout the engine operating range. Products such as the Techlusion TFi box and Power Commander PCIIIUSB are able to modify the fuel injection curves. You can also have your stock ECU remapped by a dealer. Remapping should be done on a dynamometer for best results.

I'm not gonna find pictures of every exhaust out there for the SV, it'd take all the fun out of researching the info on google, a task that you should be able to do on your own with the information provided above.

Feel free to post pictures of your exhaust in this thread.

Re: Second Generation SV650 Exhausts

Avid, your pic of the M4 high mount is actually their "race mount". A bit higher than low and a bit lower than hi, they are the only ones I know of that make a race mount.

Fixed - I knew they had three variations, I just couldn't remember what order they went in.

Holeshot highmounts on a pair of 04 SV's :thumbsup:
