WIth all the different companies, and pipe codes (53,86,2050,2013,2066 and so on) out there, is there a chart anywhere letting you know what pipe is basically the same as another??

it would really have to be an independent study , so many brands of pipes , engines . some pipes suck performance out of an engine and some pipes are the only pipe that really make the engine perform to its full potential
i have alot of this knowledge in my head top secret stuff and all my info only applies to nova based engines
happy motorin',

Hey good question! I have been meaning to post a new thread for a while now, asking what the numbers mean?

I assumed they were the volume or length of sections so a 3 chamber had 3 numbers but then I see 4 numbers and no 2 number pipes for 2 chamber ... so I think they mean nothing right?

efra numbers are what they are , numbers designated to a pipe . some are relations to volume and chamber lengths and some are just numbers .

As I suspected... they are an approval number form EFRA or FEMCA etc???

Damn... I would be nice to have a descriptive number that relates to the size of the 1st 2nd and 3rd chambers ..... so for example, you could look at a 1234 and know it was the same as a 5678 but had a tiny bit more bottom end.

I would love the engine manufacturers to put out a list of the pipes that suit their engine.

The numbers on the pipes mean nothing. They are just a homolgotation number.

Perhaps we should start a 'what pipe for what motor" thread an make it a Sticky?

Eg: people post a motor or a pipe and what works with it.

Go Tech 5 port. Go Tech / FEMCA 0801, Hong Nor 2047 or Dynamite 086.
