How I wish someone would design a 1-piece pipe where you can adjust the pipe length...

With 2-piece pipes you can adjust overall pipe length to tune your engine better. But the tradeoff is that the pipe length can change if you hit the pipe, or the pipe can come apart.

I use 1-piece EFRA/ROAR pipesets on both my S710 and S835 cars.

On my S710 I am trying the #2170 pipeset (TP06) this season (I used a Dynamite 1-piece pipe on my Impulse Pro 2 years ago).
On my S835 I use the #2690 pipeset.

We run on a smaller, more technical track (parking lot).

The Dynamite pipe was okay but not terrific. I could never find the "sweet spot" on the engine, but that may have been due to many factors and not just the pipe.

I'll admit that I "cheaped out" and went with the Dynamite pipe (flat black finish) because it was noticably cheaper than the NovaMega pipe. The exhaust header on the Dynamite pipe was a bit on the skinny side.

Yup!

A skinny header will not pass the exhaust gasses as well as a wider header. Pipes with skinnier headers usually give better bottom-end. Pipes with wider headers usually give better top-end.

I looked at some of the older headers that some of my racing buddies use. Some are so thin (the old headers, not my racing buddies ) that you could not stick your pinky finger in them. Some newer headers are much thicker... by 30~40% probably.

Default Understeer

Hi guys. Wondered if you could help me here.
The tracks in my country are on the sliperry side and I am having a heck of a hard time trying to get rid of on-power understeer from my 710. I use ball diffs front and back. I have tried lower shore foams in front to no avail.
I would appreciate it if you could point me in the right direction with regard to shock oil, shock shaft clicks, etc. so I can kick some Mugen and R40 butt!!
Thanks guys.

On power understeer .. I think Hard Diff will help !! ... or lower the front roll center . You also can play with caster ...More caster will give you more at on power streering !! If I'm not wrong !!.

Softer shock oil and spring will help too !.

Set your rear upper inserts to UBO and turn in your upper pivotballs 3 turns in.
Set your front diff to mid/hard and your rear diff to mid/soft
Also set your front anti-rollbar to soft or don't use it.

Everything else use standard

Try a higher # droop on your set up gauge, the less the front wheels hang down when you excellerate the less rear traction you get under excelleration, you could also run less rear toe in, this will make the car rotate better in the corner and give more on power steering
