Down Pipe, Exhaust, TA Performance, 1986-87 GN/T-Type, External Wastegate

1986-87 Buick Turbo Regal Downpipe, (External Wastegate), by TA Performance

TA Performance stainless downpipe for an external wastegate; 3" or 3.5" diameter.

Give the turbo Buick a less restrictive outlet with this TA Performance mandrel-bent stainless steel downpipe. Designed for the 1986-87 turbocharged Regal application, its smooth tubing supports exhaust flow and is intended to improve throttle response and power when matched to the engine combination. Choose the 3" or 3.5" diameter for the planned exhaust. This version is configured for an external wastegate. An oxygen-sensor bung and installation hardware are included. TA Performance builds these downpipes in the USA for its own headers and the stock header installation; the original heat shield requires removal or modification when used with stock headers. The pipe does not fit ATR headers or 1985-and-earlier turbo Buicks.
