Talking Exhaust Pipes. Which Numbers Mean What and what will it do for my motor??

I have a question.

There are numbers like EFRA 9886 and so on and so forth.

Does anyone have a list of all the numbers and what they do for motors.

Several New motors have come out and they don't work with the pipes I have.

Example, Ofna has a P3 pipe which works wells with some motors, but doesn't

work with others. It's not a numbered pipe like the EFRA mentioned above but,

there are others that are.

Looking at Amain, there are the following

2013
2035
Losi 2050
Dynamite 053
Dynamite 007
Thunder Tiger 2039

And So on and So on.

Help. What does it all mean???

Can I make a science out of it??

Thanks

I wouldn't get overly concered with the number on the pipe as it either an efra number or just a distinction for an individual manufacturer.

Efra 9886 is an 086 pipe designed for top end performance. It works killer on most 5 port engines. I run the Dynamite version on my P5XLT and it hauls azz!

2013 Werks and a few other brands is a good all around pipe with excellent low-mid-high end performance. Especially on the Werks B5.

The 2035 Thunder Tiger/Associated is a good 3 chamber mid range pipe that has good all around performance on certain engines.

2050 Losi/OS/Axe Rossi is a solid mid range pipe and works good on V-Specs and some other motors

Dynamite 053 is a great mid rage pipe as well

Dynamite 007 is a bottom end pipe and works good on most 7 port motors that I've used mine on.

2039 Thunder Tiger is a short 3 chamber pipe entended for top end performance.

Most pipes are designed for a specific power range and work better on certain engines. It would benifit you to ask what pipe works well for the engine that you have or the engine that you're looking to purchase.

I'm sure the OS 2050 would work well. I've also seen those motors do well with the RB 2045.

For an RB you need the RB 2045 pipe.. All other pipes will work, but none of them will let the engine sing like the 2045. Go to RB's site to figre out which header works best with your set up.. Either a 98mm, more low end, or 92mm, slightly more top end..

One of my fellow racers who runs for Werks ran a 2035 Thunder Tiger last summer on his B7 and it was flat out awesome. Good power through the whole range. I'm sure there are other pipes that work good as well.

I really like the dynamite platinum series tuned pipes. They have pipes for each rpm range available and can be bought for cheap on ebay. Just supply your own header. The hard adonizing matches the parts on my buggy and truggy and looks great. They also reinforce the stinger so they won't break easily. I've been impressed with the performance but i run go engines.

Cool

Just purchased two OS .25XZ's to try in my 8T 2.0. Have OS 2050's now but what do ya'll think. The 2050 is awesome with my V-spec's I just wonder if it's a little restrictive on the .25. Comments, PLEASE!

Go with the werks pipe, if you look at it on amain and read the specs it will say to run a werks pipe. The tuned pipes recommended for this engine are the Werks 2013 for strong bottom end power delivery, or the 2057 for increased top end.

What pipes do are alot of diffrent things, a good combo pipe and engine will add longer run time and etc. Some tunned pipes just put on an engine will hurt power and run time. Basically you look at the engine you want and you see if there are any prefered pipes for it. Some pipes can also add more bottom end or top end power. Any pipe will work with any engine but the pipe can restrict the power of the engine or it can add power.

Tricky statement.....
Basicly a pipe is designed for a type of engine with which the manufacturer thinks he can use on big (EFRA/FEMCA/ROAR) events. The performance of a 2-stroke engine stands or fals with the choosen pipe and one pipe can make one engine a beast and the other a disaster.

The choice of a pipe cant go wrong if you find out what loplevel drivers with that engine drive or what others are using.

If you are on a club you can ask fellow clubmenbers to try some pipes of them and find out which one you do like.

I fail to understand your comment? How is my reply a tricky statement when it's basically the same thing you just wrote in not so many words? Ask what pipe works best for a particular engine is what I said....
