Hey guys,
We have just tested the Helix prototype exhaust and got very good result with it. The exhaust sounded a little deeper than the stock exhaust and produced great whp gain. Also, please keep in mind this is a stock 05 350z with no modification except for the exhaust.
Here are some pictures of the exhaust:

Here are the dyno graph (4wd Mustang on 91 octane):
Before (stock Z):

does this exhaust have the same connection point between the b-pipe and muffler inlet as the stock? if so would the b-pipe be available for sale? i have my SECOND sp2 muffler coming next week that would match well

The target price is $599 for this exhaust.
