Maybe the power difference between the two is the dyno's that they were tested on.

I went the other way. I did a full turbo back, as this was easier to install, but a little more costly. I like the sound too...

[Could the differance between having a flex pipe and not change the power rating?]

I noticed that too, is there an advantage or disadvantage to having a "flex" in the uppipe?

Advantage: potentially less stress on the turbo.

Disadvantage: potential leaks at the flex joint

Up-pipe & Downpipe

Nothing against Vishnu but for the prices of their up-pipes & downpipes I would rather spend much of my $$$ towards the Helix Flex Up-pipe & the Helix Bellmouth downpipe...

One thing about the Helix downpipes make sure you get the USDM-spec downpipe if you have a USDM-spec catback system.

Save your $$$ & get both...
