Default Looking for some tuned pipe feedback.

Guys, the following is a list of some of the .21 size tuned pipes available from various manufacturers around the world. The description is based totally on what the manufacturers have stated, not through personal experience, so is intended as a guide only.
Please note, the list is not comprehensive and will be added to as I gain experience and knowledge.

Any ffedback that you more experienced guys can give would certainly be greatly appreciated.

Hong Nor
  • PI-812H - excellent mid-range and top-end speed without bottom-end torque sacrifice.

  • PI-809 - high torque and can also offer a wide spectrum of RPM.

  • PI-811 - more initial low end power

Jammin
  • JP-1 - The pipes shape gives excellent bottom-end snap and mid-range.

  • JP-2 - The pipes shape gives excellent mid-range and top end without bottom-end sacrifice.

  • JP-3 - This new pipe is a 3-chamber design with all around performance, very similar to both JP-1 & JP-2 combined.

  • JP-4 - Longer smoother power band than the JP-3. The power band is concentrated on the mid to top end range.

Dynamite
  • 053 - smooth mid-range power band and is best suited for medium sized flowing off-road tracks

  • 086 - exceptional power for sustained high rpm applications. Best suited for large flowing tracks with long straight-aways

  • 007 - smooth bottom end acceleration and has an excellent mid-range power band

Team Losi
  • RE11 - Better mid- to top-end power, Smooth linear power band

  • RE10 - provides immediately gratifying explosive power

Novarossi
  • 9853 - designed for excellent mid range and bottom end performance

  • 9863 - designed for bottom end performance

  • 9886 - good top end performance, but it also has excellent bottom end performance

  • N51013 - EFRA 3005 - This pipe is considered a bottom/mid range power pipe

OS Engines
  • T2050SC - providing excellent bottom end and top end performance

  • T2060SC - providing excellent bottom end and top end performance.

Sirio
  • EFRA 2057 - designed for smooth bottom end performance

  • "EVO III" - EFRA 2013 - produces great top and bottom end power

RB Concept
  • 01350 - EFRA 086 - Top or bottom end depending on manifold length.

  • 01351 - Top or bottom end depending on manifold length

OFNA
  • 053 - designed for mid range and bottom end performance

  • 063 - designed for bottom end performance

Team Orion
  • 88217 - EFRA 2013 - designed for excellent all around performance

  • 88220 - EFRA 2057 - designed for smooth bottom end performance, slightly better run time when compared to the EFRA 2013

Team Associated
  • 2035 - combination of bottom end punch and top end performance

Werks Racing
  • 2013 - designed for good top end performance, but it also has excellent bottom end performance

Axe Rossi 02121 - EFRA 2050
  • designed to provide excellent bottom end and top end performance

Go Technology
  • 0801 - three chamber pipe which is designed to improve torque on the low-end, and quickly achieve top-end speed

MR Ninja
  • 15001 - EFRA 2053 - pipe is designed for all around performance

Trinity
  • Adam Drake Picco 069 40023 - designed for good overall performance, but it also has excellent bottom end performance

I would say it depends on the engine. The grp .21 engines really like the 053 pipes the grp 2053 makes less power but a little better mileage and the dyn 053 opens the power up and cuts off a little runtime. The same dyn 053 pipe on an os speed engien did not perform at all it was ok but compared to the os 2060 te 053 chopped off the top end and was a little soft on the bottom. On the os speed engines the os 2060 or mugen 2042 (same pipe) works very very well. Well worth the $$ they get for it. I didn't like the 086 on either engine or a grp .28. The trinity bad boy pipe has a total of 2-3 laps on it and back in the box it went. It cut the top end off worse than the 053 but I know some guys who run them and like them. That's just my experience. So once again I think it depends on the engine. Any 053 pipe seems to be a safe bet for descent performance. That's what's in my pit box.

Not to hijack this thread, but since were on the subject of pipes I need to ask. Is there a difference between on road and off-road pipes besides the headers? Such as a Sirio on-road 2013 and off-road 2013?

Yes there is. In the case of the Sirio pipes, the 2013 on-road and off-road pipes are completely different. The on-road pipe is considerably shorter and has less volume. It's made for an engine that runs at much higher RPM and that has more advanced timing in all respects. I can't speak for other brands, but there's definitely a difference with the Sirio, Werks and Trinity pipes.

Since they are different why would they have the same EFRA number? That is what really gets me confused.

Wouldn't they have changed the number since the pipe is different?

I'm not familiar with the EFRA approval numbers and how they apply, but apparently they're comfortable with using the same approval number on completely different pipes. Perhaps they were submitted at the same time and therefore have the same number? Only a guess, but they're definitely different pipes.

Have you tried running the on-road 2013 on a off-road engine. I ordered the wrong pipe and now I'm debating whether to run it or send it back.

You're right. The pipes were submitted to the EFRA Homologation Officer on the same testing invoice. The EFRA officer does the testing and if they pass he issues a homologation certificate to the manufacturer with the EFRA number. (http://www.efra.ws/rules/Handb09Generall.pdf, Page 42)
