My bike had Cobra slash cut slipons already installed on it when I purchased it. I ran these pipes for a while, but I felt that they were a little too loud and it seemed like the bike would wind out quickly and would not build any additional power with increased throttle input once it hit a certain point. Therefore, I saved for a new set of V&H slash cut slipons. These were not as loud and seemed to let the bike build power longer with increased throttle input. I theorized that the Cobra slipons were less restrictive then the V&H slipons and that the perceived difference in performance was due to the bike needing a certain amount of back pressure in order to perform well and that the V&H slipons provided the right amount. I am not sure if my theory was correct or not, but I have been very happy with the performance of my V&H slipons. However, I wonder if a full aftermarket exhaust would be even better than the V&H slipons or not? If so, is the difference in performance worth the difference in cost?

Good question Dave. Please forgive me as I've forgotten which yammy you're riding, it's 9 degrees outside so my brain is a little bit cold.
Judging from your avatar it appears your bike has true dual exhaust. When I did my research for aftermarket exhaust after purchasing my 950 tourer, I found that for maximum performance, not mpg, but performance, opening up the exhaust is only part of the game. I spoke to three Yamaha mechanics and researched the Internet in depth. All of the mechanics stated that there wasn't huge differences in exhaust brands, however when you open up the air intake system along with the exhaust, you'll get the best performance gains. I didn't notice if you'd done any mods to your air intake, but I'm just passing along what my research found. Personally I like the looks of true duals, however my bikes research showed keeping the 2into1 with an aftermarket slip on gave better torque, and throttle response. At the time, and even now I couldn't afford the $700 price tag for the true duals and an open air filter kit and a fuel processor since my 950 is fuel injected. At that time to get my ECU reflashed was around $500-$600 with an undetermined down time while it was being sent off for the reflash.
I do know that after I added the cobra slip on, I had a bit more performance and great sound. After the open air filter kit and fuel processor to compensate for the upgrades, much better performance all around. This was just my findings and I hope this helps. Please keep us updated on what you decide on.

My Roadstar had a set of V&H slashcuts on it when I bought it. the mechanics who did the road worthy had stuffed them full of fiber glass and some perf pipe to get the noise down. Needless to say it ran like a dog. when I took that stuff out it ran great but was very loud. I ended up fitting V&H quiet baffles and putting in these baffles I got from Germany as well which are a straight perforated tube wrapped in muffler felt. the performance seems good and the bike has a nice mellow rumble without being obnoxiously loud.

Can't say much for performance, but in terms of looks and sound the Cobra Speedster Longs that I put on my 1100 Custom this summer are the mutts nuts. I live an urban life, and so installed the Quiet Core baffles as well, the sound is still amazing but man if I lived in the sticks I'd've kept in the stock baffles. Even with the Quite Cores the sound from these pipes is fantastic, they look rad on the bike and now she sounds like she should. Can't recommend them enough.

In terms of performance I think there may be slight benefits, but none I noticed. I'll be honest, I did it for looks and sounds. I'm all about that sh#t =)

Now I'm going to show her off...

I noticed a difference too after opening up the restrictive stock airbox. I had a Maxair Predator pod kit installed shortly after I purchased the bike and it improved the responsiveness of the engine and it seemed to increase the horsepower too.

Yes, the V&H slipons are definitely loud. However, I think the sound pales to the loudness of my COBRA slipons. The V&H slipons have a sharp crisp bark, but my COBRA slipons were very close to the sound of straight pipes when I twisted the throttle or when the bike was lugging at low RPMs!

They look cool and go well with the bike!

If you are riding an 1100 with the stock head pipes, and have pods, you'll see a pretty good performace increase going with full pipes. The stock ones are extremely restrictive. Open it up to let more air flow through the carbs, you'll pick up another 5+ HP.

You'll most likely need to bump up the main jet size depending on what you've got in there now.

When I had my 1100, I had the V+H slipons, a pod set up and rejetted my carbs. For me that was enough rumble and power gain. I loved that machine because it was so well balanced and it gave me a bad case of permagrin ;). I found that that was enough for me at that time. After a while, I wanted to have more power so I upgraded to a Strat. Maybe saving up to get a more powerful bike would be something to look at if that is what you want.

Great looking bike Jimbo, nice photos too.

I love motorcycles, but if it was up to my wife I would not have any motorcycles at all! It is not worth the battle that I would have to go through to get another bike. I don't think our marriage would survive it! Therefore, it is easier for me to increase the performance of my V-Star 1100 with performance mods, than it is for me to convince her that I need another more powerful bike. Besides, I like the high revving nature of the V-Star engines.

Dave,

Where abouts in NJ?

I just did the full exhaust setup on my V-Star 1300 and its def loud, but manageable. I'm sure its just about as loud as you doing the slip on pipe.

I was told by the place that sold me the exhaust to invest in the power commander to full open the full potential of the bike since it came restrictive from Yamaha. I plan on doing that very soon by visiting the guy Ivan up in Rockland County NY

I would not invest in the power commander. Get Ivan's flash first then you really unleash the beast.

Both the 950 and 1300 should have a fuel management system with a full exhaust. They already run lean from the factory. It runs even more lean with exhaust or intake mods. The factory computer cant make that big of an adjustment.

Yeah it runs. but not as optimal as it should.

Just a piece of advice. Its been tested and proven.

But a slip on is fine without any fuel management.

Ivan's flash maybe all you will need, it changes the timing, fuel curves, mixture, throttle mapping. He suggests a power commander, (the old simple one) with air and exhaust mods to get the max performance out of the bike, but unless you run hard with the throttle wide open, it may not make much of a difference. I will say Ivan's re-flash is the 100% best mod you can do do any Yamaha Fuel injected bike.
