Replacing the restrictive factory downpipe is a very popular upgrade amongst owners of turbocharged vehicles. The popularity of downpipe upgrades can be attributed to the low cost-to-high performance ratio of the modification. Performance downpipes typically produce a sizeable power gain at a comparatively modest cost. In addition to power gains, an upgraded downpipe will help reduce turbo spool time resulting in a more responsive engine. These benefits, coupled together, make a performance downpipe a very appealing upgrade for those searching for the most from their vehicle.
Turbocharged engines operate best with zero back pressure in the exhaust system. Performance downpipes reduce flow restriction/back pressure by increasing the piping diameter and replacing the restrictive catalytic converter with a high-flow cat or straight pipe. The result is more power and quicker spool time from your turbo. It should be noted that any downpipe that replaces your vehicle’s only catalytic converter is for off-road use only. We recommended catted downpipes in most cases for the best compromise of performance and legality.
