Just clamp-on, no screw! The SUPERCIRCUIT downpipe is made of full 304 stainless steel mandrel bent pipe and full TIG/Argon welded on high precision CNC machined stainless steel flange to ensure perfect fit (SEE BELOW).

At the other end of the SUPERCIRCUIT Downpipe is a slip-on joint where it is connected to the factory stock catback exhaust system. The downpipe is 100% compatible with the factory exhaust system, no cut or weld is required during the installation.

The SUPERCIRCUIT Catless Downpipe is ideal for ecu tuning or ecu reflashing needs, even though it can also be installed alone without tuning. CEL issue can be countered with a Mini Cat or an O2 sensor defouler.
