E36 Active Autowerke Track Pipe
I have an AA Track pipe for sale.
Here is a bit of info from Turner Motorsport:
"This track/racing center exhaust for the E36 325 and E36 M3 replaces the heavy and restrictive stock catalytic converters. On a 1995 M3 this exhaust alone showed gains of almost 20 HP and 15hp on the 1996-1999 M3! It bolts to the stock exhaust manifold or the TMS Shorty Headers without cutting or fabrication. The system features 100% stainless steel materials, a straight through, no restriction resonator, 3" inlet pipe with stock diameter twin tubes, and total bolt-on design using stock type flanges and hanger points. The racing Track Pipe is nearly 30% lighter than the factory cat section! We recommend using this with the Borla cat-back muffler, because of its light weight, great sound, and proven performance gains. Sound quality is refined, not overly loud.
This exhaust includes a single oxygen sensor port for OBD-1 models. For an OBD-2 E36 M3, the use of oxygen sensor simulators is required to keep the Check Engine Light off (optional add-on below). Note: while this track pipe will fit the E36 328i/is, the O2 simulators will not keep the Check Engine Light off. "
I will post pictures later today. O2 simulators are included. This package is $925 from Turner
