Just curious how many people have got one and how much diffrence did it make?

 

if you are plannig on getting the helix one, don't. i got one and it did not fit and turbotrix know their stuff. get the dnp one or the ams. the gains won't be that great if you don't upgrade the turbo exhaust housing too (10.5 hotside).

my 2 cents.

 

Ummmm Alot of people on this board have installed the Helix O2 housing with success.

 

i like mines...
