Y-Pipe and Exhaust

Wilhelm Raceworks Y-pipe for 2GR-FE

The Wilhelm Raceworks Y-Pipe connects Frankenstein Motorworks headers to the Berk Technology muffler.  This pipe is for the old style tubular headers only.  They will not fit the new Frankenstein Motorworks cast headers.  304 stainless steel TIG welded construction, with 2.25" pipes before the merge and 3" pipe after the merge.  Includes stainless steel hardware for connection to both the headers and the muffler, as well as a gasket for the Y-pipe to muffler connection.

If you need a catalytic converter for an emissions test or just don't like the smell of a catless car, I can add a Magnaflow metal core cat to the Y-pipe as shown below.  The only catch is, it's a very snug fit.  The lower most bolt on the rear e153 transmission mount must be removed, and you may need to run polyurethane engine mount inserts to reduce engine movement.  I can also modify existing y-pipes in this manner, please contact me to discuss.  Note, this catalytic converter is not CARB legal, and this y-pipe with cat will not help make your swap legal in CARB states.  However it should pass most basic emissions tests.

Please note that this y-pipe is designed to be used with the E153 transmission, and clearances are very tight around the axle and CV joint when the S54 transmission is used with your 2GR swap.  The version with the catalytic converter will NOT fit with the S54 transmission.

Typical lead time 3-5 weeks.

For those looking for something a little out of the ordinary, the Wilhelm Raceworks exhaust for the 2GR, features a twin tip center exit design and with a Borla Pro-XS muffler and Helmholtz resonator.  Not only does this provide a unique look and awesome sound, it also saves about about 15lb off the back of the car compared to the Berk Technology muffler.  Please note that this exhaust requires the rear grill be modified or removed.  A rear diffuser to complete the look of this system is also available.

This exhaust is a little on the loud side.  It will generally measure 97-98db at ~50ft, so please keep this in mind if you have specific sound restrictions to meet.  However, cruising on the highway or around town is reasonably quiet in the car with the addition of the Helmholtz resonator as described here.  A set of tip silencers drops the WOT sound level by a couple db (95-96db typically) and quiets the cruise sound levels a little as well.  A little work is required to fit them, contact me for details.
