Anyone using the spark double high exhaust?

ive done the D200

What does the other side look like? I don't think I've ever saw a photo of the left side with any of the under tail exhausts.
 
I got rid of my termi d200 and changed to the spark 3/4 side exit with a choice of different cans.

The termi is a lot of money and it was playing on my mind if you crash either side it'll fubar it.

Obviously ... stay with the std and just ride...
 
The D200 does seem to use an abnormally high amount of tubing. Like someone at Termi's design studio had a brother-in-law at a titanium tubing supplier who was short on his sales quota.

Cost wise, I like SC Project's offerings, in particular the full system @DeussenEngines said he got the best results from in the dyno. It looks funky with the OEM lowers, but with a full pan or the Akra lowers with the block off installed would look like it made more sense.

I'm not the resident expert on exhaust but I think the idea is longer pipes gives you more top speed. I'm sure there is a declining maximum to the length and I agree it just feels like Termi is pushing the concept a little haha. These SC Projects are the best looking by a long ways if you ask me.
 
I think we need an engine tuner in here, but I've never heard of more tubing being better than less. I've always heard equal is important. Maybe Termi wanted to maximize the amount of equal they could get and made them longer in the process.

That SC Project I listed is $2,941 USD on the manufactures website. For a full system no less. You could get three of them for a dealer installed Akrapovic under tail.
 
While equal length is a primary consideration, utilizing the straightest piping is just as important. That’s why the rear bank on the MotoGP bikes look so long. They’re as straight as possible. Note the front bank exits further forward, but straight as possible within the package.
 
I just finished install of the Akra system on my ‘21 SP and the rear bank pipes wrap under the front bank pipes to keep them as straight as possible within the lower positioning.

The Termi system blocks the key access for the GPS/DDA, so not a user friendly design.
 
In general, longer pipes increase low rpm torque and shorter pipes increase high rpm power. There are several variables like valve lift/duration, port length/design, etc that can affect the optimum pipe length for a desired engine performance characteristic.

You would need to know more details of specific engine parameters to make an accurate assessment.

I was under the impression that SC system had been discontinued. No?

To my understanding, that’s true for forced induction applications - the best exhaust is NO exhaust. But for NA applications, exhaust tuning is important for scavenging effects, and a longer exhaust ‘might’ be beneficial.
