Which boost tubes are the best?

I have done a ton of searching on here, but unfortunately haven't found anything leading to a solid recommendation.

Alta tubes - silicone - claim 10 WHP, but dynoed car had a lot of modes
NM Engineering - Good Company, can't find dynos
Denjon - has both sides as hard pipes

Are these mods worth it?

Currently I have:
AEM Intake, Accessport Stage 1 FMIC map, Rennestil catless downpipe.

If anyone could give me some solid knowledge, I would appreciate it! I don't want to drop $400 on tubes if it's not worth it. I have a 2012 JCW so another option is the muffler delete for >$30

 

Not worth it.i had them all changed and noticed nothing except for a bit more turbo hissing but no power.

 

The factory has many things scienced out well on this car

 

Forge has a hot side for $160.
