Quiet can on my viper

[Studroes144]

Been real impressed so far with the info I've been hearing from people that are putting cans on their vipers. Seems like it's a good bang for the buck. I was planning on getting an exhaust for my viper but was scared of how loud most of the cans are that are out there. I don't mind the noise personally but there are pretty strict noise regulations on out NY trails so I didn't want something too loud but at the same time still wanted decent power gains. I've had the D&D quiet can on mine for a few days now and finally got the clutching dialed in for it today. It took all day to get it right as it seemed as tho any little adjustment changed it drastically on the rpm scale. We started off with my viper against another viper ltx. Both with very similar clutching. Bone stock with just clutching on both sleds, mine would get a sled length jump out of the hole on both dead stop starts and roll ons, mid range the other would come back dead even and the. I could pull about half a ski length on top so we had a real good comparison to go by. Now with the quiet can on mine launch and mid range didn't change at all but from 60-95 it pulls really hard. I went from pulling half a ski length at 100 miles per hour to pulling 2-3 sled lengths at 95 mph. Good bang for the buck there. It's got a nice sound, not too loud at all but can still tell it's flowing more air. I posted a vid on YouTube for anyone who wants to hear it. The chain case adjuster bolt is accessible as well. Its not wide open like the other loud exhausts are but you can adjust it with the can on so in very pleased about that.

Thanks for the review Barry. It sounds good. What do you think the approx. weight loss is?

I will try to weigh my stock can then weigh the quiet can next time it is off. There is t a huge weigh savings but certainly a real good power gain

Awesome, thanks.

What is the video called on youtube ?

Just search my name, Barry Roes. Quality isn't very good but can hear the sound

Where did you order from? How much was it?

 

[Studroes144]

Yes you can get to the chain adjuster. $480 from D&D. U can look them up online

Just had the quiet can off mine to weigh it. I'm sure these aren't exact numbers as I just weighed it on a cheap bathroom scale. Stock muffler appeared to be 12-13 pounds and quiet can was 8 pounds. I'm true true weight numbers will be a little different from that but looking at roughly 4-5 pounds lighter and adding 8hp and some torque as well.

Access to chain adjuster.

Sounds good thanks so much.

Did anyone do a DB test? I'm guessing it's just over the NYS limit but probably ok if you don't act like an idiot. Any impact on mpg, seems like the cans are leaning things out a bit. Of course if you use that extra 8hp it needs more gas.

 

[Studroes144]

Never checked gas mileage. No risk of running too lean with just the can, stock mapping can easily keep up with it. With an airbox mod or filters you'd certainly want to get some type of programmer for more fuel. No db test. It's a little louder than stock but not much, wouldn't cause any noise complaints
