The most significant differences among these pipes are construction.
CP-E downpipes use cast flanges that neck down to 2.5" at the first bend off the turbos. I like that for its durability over heat cycles from a daily-driven car.
The ar Design pipes are quality mandrel-bent, welded pipes that neck down to 2.5" at the secondary pipe flange. Seemingly hundreds have been sold without issue. Ceramic coating is optional.
These AA pipes appear to be constructed with quality that rivals ar. In addition, they include mounting brackets that help to suspend the front portion of the exhaust system and control lateral movement as the engine flexes under load. The price in this group buy is hard to ignore-- these AA pipes look to be an incredible value.
