Actually the pipes would benefit any setup in more ways then one actually theres around a dozen reasons, but heres a few without stating the obvious reasons why.

Theres probably a reason why the factory RS4 pipes are nothing like the U.S k03 pipes and much larger and not plastic.

1) .065 wall aircraft grade aluminum U.S certified, all mandrel bent & very smooth on the inside.

2) The diverter opening on the factory pipes are tiny, improving this area helps in boost response and creep for one.

3) The factory pipe fits .5 inch in the boot these pipes fit 2.5 inches in the upper IC boots keeping the boot and pipe in place also eliminating any flex in the boot.

4) Factory pipe changes shape and size 5 times these don't.

5) Already setup with meth bungs welded on & wrinkle coated in black.

6) Upper pipes fit further into the T.B boot with a very aggressive bead roll on both ends, will never pop off especially when coupled with a proper clamp.

7) Will leave plenty of room to grow and won't heat soak as bad as the factory or others.

Just a few reasons.

And it is ideal to place the nozzlers 6 inches before. These allows for you meth to cool the charge in the most efficient manner. Too close to the TB and it doesn't vaporize with the charge and you could end up with a fubar'd throttle body after time.

It all meets and mixes in the TBB anyways.


I think it'd be fine as long as you can secure the nozzle bungs in the plastic good so they don't leak.
