3" TURBO DOWN PIPE 944T KKK & T4 Thermal Coated version on left, standard finish on right. Both KKK Style. Lindsey Racing's 944 Turbo 3" Turbo Down Pipes for both the KKK (stock style) and T4 turbine housing turbos. These utilize a three stud and nut connection to the primary exhaust like the stock exhaust does. However they will not connect to the stock exhaust because the bolt circle or bolt pattern is larger. If you are ordering one of our Lindsey Racing 944 Turbo exhaust systems as the same time, you would select the exhaust system for the Lindsey Racing Down Pipe. Then we configure the exhaust with the correct flange to bolt up directly to our Turbo Down Pipe. If you're wanting to add the turbo down pipe to your already owned Lindsey Racing Exhaust System or a Fabspeed exhaust system, our adapter flange must be used on that situation. If you're running a larger turbo then the stock K26/6 or k26/8, then you need a larger down pipe for maximum performance. It doesn't make sense to put on a larger turbo with a larger turbine wheel only to choke it off with the flange of the stock down pipe you're bolting to it. You want a Turbo Down Pipe that allows the exhaust to escape the hot housing without restriction. The ID or inside diameter of the inlet of our Lindsey Racing Turbo Down Pipe is 2.6" which is the same size hole that that is machined in the turbine housing for a P-Trim wheel which is used is some of our larger turbo's. So whether you are using a Stage 3, Stage V or a P-Trim turbine on the turbo, this Lindsey Racing Turbo Down Pipe will accommodate them without restriction.  The turbine exhaust outlet opening on a K-26/6 turbo (standard on 86-88 944 Turbo) is 1-15/16". On a K-26/8 found on the Turbo S models, it's 2-3/16". Both of those turbo's are a nice fit for the stock/original turbo down pipes flange opening. Once you go larger on the turbine opening then that, then the stock down pipe becomes a restrictor plate. Even a small entry level Stage 3 turbine has a opening of 2.3". So using a Stock down pipe on a Stage 3 or larger outlet turbo is cutting your potential power by restricting or blocking off the benefit you would be trying to get from using that larger turbine.  Turbo Down Pipe Includes:
 Our Lindsey Racing 3 and 4" exhaust systems can attach directly to this down pipe. If you order a exhaust system and select the down pipe option, the correct mating flange is on the next pipe down stream of the Turbo Down Pipe. If you already have a Lindsey Racing 3" or 4" exhaust, fitted to a stock down pipe, you can get our adapter flange (pictured below) which can be welded in place of your current flange. You simply cut your pipe near the flange, test fit, and weld this adapter flange in place.
