How do you tune a Tuned pipe.
I got a MIP side pipe kit and the manifold/header is really long.And I have read on other sites that it is so you can tune if to fit your engine by slideing the pipe forward, But how do u know when to move it forward or backward.
Or am I way off and all u are supposed to do is bolt it on and go.

The longer the manifold, the better your top end. Shorter for better off the line punch. It's according to your preferences. Just experiment till you find the spot you're happy with.
 
Rolex, I think you have it backwards. The longer the header the more low end punch you will get, the shorter it is the more top end you will get.
 
Hmmm, now you've got me confused, but I THINK I have it right. When I had the Humm-V body on my Maxx, I had enough room to extend the manifold and run the tuned pipe diagonally, and out the driver's side rear window. Major top end.
When I got the Jeep Rubicon body, I had to shorten everything since there was no high roof in the back to clear the pipe. That changed everything, as far as the high end performance. I'm getting another Humm-V body and going back to the original set up.
We'll wait for other opinions on long or short, but I'll bet you a Rum Egg Nog.
 
Keep the nog, but I'll bet ya the rum, lol.

Heres a quote from rcnitro.com

The header's length has a significant impact on performance. It's much like a trombone: you slide it out farther, and it resonates at a lower pitch. Slide it out less, and it resonates at a higher pitch—same thing with tuned pipes. Experiment by cutting 1/8 inch at a time off the header, and run the engine between cuts. The idea is to keep cutting until, as the boys from across the pond say, it's really "on song." That means the engine and exhaust system are in sync and singing in harmony. This is when the engine makes the most power. The rule of thumb is that a longer header is better for bottom-end power, while a shorter header makes your engine scream on the top end. You can go too far in either direction, so don't be reckless; you'll do more harm than good.

Its taken from this great article on tuned pipes.

Interesting info, NCNitro, but it didn't work that way with mine. I'm using a MIP metal pipe, originally on a .15, now on the 2.5. With a copper 90, and tube extension, I had amazing top end. Maybe the 90 had an effect on where or how the pulse affected the tune.
We'll wait for a few other replies, but just in case you're right, I'll send you the Nog. The rum is almost gone.
 
Thanks guys.your answers have helped alot.
The one thing that is weird to me is that when more of the manifold is in the pipe a smaller manifold,my maxx has awsome bottom end all 4 tires rip and dig in to the ground but when I move th pipe out my recivere gets in the way so I dont know what the top end is. do u guys have this prob.or did u guys move your reciveres
 
I changed the manifold so I could run it out the back. The receiver wasn't an issue.
That's what I got also, Tarant, the shorter the system, with more manifold inside the pipe, hotter bottom end. Extend it, or lengthen it, and raise the high end.
