Y-Pipe and Exhaust

Wilhelm Raceworks Y-pipe installed

The Wilhelm Raceworks Y-Pipe connects Frankenstein Motorworks headers to the Berk Technology muffler.  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 pretty snug fit and the lower most bolt on the rear e153 transmission mount won't fit any longer.  However, I have been running my car for over two years without that bolt and so far I have not seen any reason it is necessary.  There are four other bolts on that mount!  I can also modify existing y-pipes in this manner, please contact me to discuss.

Please note that this y-pipe is designed to be used with the E153 transmission, and the rear bank o2 sensor will be very close to or perhaps touching the axle when the S54 transmission is used with your 2GR swap.  This can be solved by bending the o2 bung down slightly, by using an angle o2 extender, or by adding another bung in a location that will clear.

For those looking for something a little out of the ordinary, I am now offering a complete (header back) exhaust for the 2GR, featuring a twin tip center exit design and a Borla Pro-XS muffler.  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.

This exhaust is a little on the loud side.  It was measured at 97db at ~50ft at a local autocross, 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 and quiets the cruise sound levels a little as well.  A little work is required to fit them, contact me for details.
