I have the 4" power elbow Bought it (and 4" downpipe) after my first upgrade to 4" exhaust. Did not know the 4 inch exhaust necked down to 3 inch before the turbo out let so basically I had 3 " exhaust still, that went to a 4" pipe. I feel the 4" power elbow gives me true 4" from the turbo back. I ported my power elbow some. If you get one you will see a flat area on it that bolts to an open area on the turbo exhaust oulet flange, I removed a bunch of the casting in this restricted area of the power elbow to improve flow more.:thumbsup:
If your intersested in a Banks power elbow I have one brand new still in the box for sale,I intended on using it but ended up getting a set of twins that came with a 5" downpipe.Make me an offer if you are intersested.
