Header-Y Pipe For 16v Porsche® 928

Hi Carl. Just installed your headers, Y-pipe and Borla on my 1982 928 Weissach edition. Love them! Tom H.

A Quality Stainless Steel Product from 928 Motorsports LLC®

Adds 25 lb/ft of Torque across a long power band!

Application: 1978-86 16v Porsche® 928's equipped with 928M Headers

Description: A bolt-in Y-pipe designed to smoothly transition from our 16v Headers with merged collectors to either the stock single exhaust or the after-market Borla single exhaust. Made from all 304 stainless.

Added Benefits: The Header-X can be used with both the stock 928 exhaust or the Hi Performance Dual Exhaust that we sell. This means you can grow your 928 exhaust system in sections, and mix-and-match the parts after the Header-X.

Catalytic Converters: We carry a 100 CPI high-performance catalytic converter for the single exhaust if you require one. It can be installed after the Y-pipe.

928 Motorsports Quality: Our Header-Y is TIG-welded from 304 stainless steel tubing, and the flanges are extra-thick for warp-free positive sealing.

Dyno Chart Note: Note that the car in the dyno chart (below) already had a Borla performance exhaust and catalytic converter delete. Our gains were IN ADDITION to those improvements!

This Kit Includes:
  • 928M Header-X mandrel bent and made from 304 Stainless Steel
  • Dead-soft Aluminum Header Flange Gaskets (2)
  • Yellow Chromate plated Header flange bolts and nuts
