Here is a link to some pics i took. The Dyno pics are from the 11-15 dyno day at XXTuning. The dyno sheets are my baseline and then with only a Z tube.

The rest are just pics I took when I was messing around trying some new stuff. Let me know what you think.

What was the gain with the z tube?

 

Stock it was...

229.1 hp
227 ft lbs

Z tube was...

234.8 hp
231.2 ft lbs

So about 6 hp and 4 ft lbs. not bad for a 2 minute job. also it still looks completely stock.

I may buy a Blitz drop in filter or a Stillen airbox to go with the Z tube.
