The GR Supra with the BMW B58 engine responds very well to a downpipe upgrade. Our stainless steel downpipe includes O2 sensor fittings and is a direct replacement for the factory unit.

Our Pro Series down pipe utilizes a 4.5" diameter upper v-band section, tapering down to a 3" section where it unites with the factory exhaust. A flex section allows for standard movement and vibration to be absorbed. Installation is straight forward for the DIY or can be done by any exhaust shop in an hour.



This is a No Cat design and is strictly for off-road and/or racing use only.

Turbo spool up is decreased, power gains are 20+ whp and there is a robust sound increase. Installation time is less than an hour for someone with experience in exhaust.

As with the deletion of any CAT's it's possible that the check engine light can trigger as it's looking for a certain amount of O2 from the comparison of the No. 1 and No. 2 sensors, which is affected by the CAT delete. The BMW DME (ecu) is very particular.

There are two solutions. For some they have had good luck with a simple O2 sensor spacer or extension for the O2 sensor (2nd sensor). Pictured below, which screws into the O2 sensor on the downpipe. Over time a CEL is certainly possible.

The second solution is what some call the CEL delete or mini-cat as it has cat style precious metal properties. These are more costly but have shown great promise. Both are optionally available in the drop down menu, but please note you do NOT need both of these, it's and either or (either the extension only or the mini-cat only. These have shown to be quite effective on B58 powered BMW and Supras.

Excellent first upgrade for the new 2020 GR A90 MKV Supra. FREE SHIPPING IS FOR FED X GROUND IN THE LOWER 48 STATES ONLY. HAWAII, CANADA AND ALASKA ALL AVAILABLE IN THE DROP DOWN MENU.
