i cant find the anti reversions

 

Woah x2!!!!!

 

thats because they are legally set up so only hytech can use them. like copyright.

 

i call BS on this. im not gonna write a book explaining the reasons why, just look up all the copyright, rights reserved, patent pending, and so on laws. then you will understand why i call BS

good luck.

OP: id say keep looking you will get one. there is no law keeping you from using that. only the owner of the product, if that is the case.

What do you mean by anti reversion tubes?

If you are talking about the parts that are put in your header at the flange try looking up Torque Cones. Other than I'm pretty sure that most of the anti reversion steps I have seen are built in using different size tubing. If your looking for those Hytech bulge type reversion tubes.....Good luck! IIRC they are made using a hydraulic press or form of some sort.

 

First of all do you know what the anti reversion tubes do and when they are effective? Or are you just putting them on just because you think they are cool.

Some motors may need them and some don't need them at all.

IMHO there is no need for AR chambers on a drag racing header. And trust me I build a few of them.

anti reversion is simple

use the next size smaller (or larger) and viola! anti reversion!!!


Ex:
First 8 inches of header (measured from head flange) use 1 3/4" tubing. The rest of the header use 1 7/8" tubing.

BTW nice choice on the head flange

Ohh yeah one other thing.
Don't mess around with Burns, get the good stuff that the real manifold builders use... CPPExhaust.com
Price is much MUCH better than burns and ALOT better quality as well

If you have any questions feel free to pm me.
