hello once again all. I was wondering if I could get some recommendations for some pipes. I just got a 48 and I want to change out the pipes to get a nicer sounding growl out of it. As well as an improvement on performance as well (if that's possible to do through pipes). Also a bit of a new riders so any modification advise or must haves for bikes that I don't know about would be greatly appreciated as well.
-thanks

 

Welcome to the forum and congrats on your 48!

You could get a great sound as well as a performance gain with Thunder Torque Inserts™.

Check out this video of the DK 48 with stock exhaust modified with TTIs-


You can hear that the TTIs will deepen the tone of your exhaust, giving it a throatier growl.

Also you will get a gain in low and mid range torque. Check out this Dyno-



This is the best exhaust mod when comparing results per dollar spent(29.95).

Here is a LINK to the TTIs.

Hope this helps.

Bassani firepower or rush slip-ons. Not only really cheap, but offers the best performance. Very close to two into ones.

As for sound? They are not called firepower for nothing.

 

I second the Bassani Firepowers. Incredible value, sound and perform amazingly over stock. Best upgrade I have thrown on my bike so far, no question.

I also bought a joker machine air cleaner I'm throwing on once I buy a fuel pak, not trying to ride too lean, ill update again once I go full stage 1.

 

My bro just put these on his 48, they are really loud but sound great. I went with Bassani's and we are both using DK Customs Thunder Torque Inserts. I'll never use an exhaust without them, they make a big difference in sound and performance.

 

 

Power is torque times rpm divided by 5252.

In that equation, if you change the torque by a given factor, the power changes by the same factor. They don't move independently, they move together, and by the same percentage. That's true at any rpm, or as an average over any rpm range. They're mathematically tied together, by definition.

Sure, you're getting a bigger gain in absolute terms over that range, because the numerical values of the torque are bigger over that range. But as a percentage, the gains track each other.
