What Straightflow states

Straightflow says the substrate is made to be welded into an existing catalytic converter housing or muffler. The metallic honeycomb foil resists vibration and high temperatures, and the 200 CPSI density gives surface area for catalytic coating while keeping exhaust gas flowing.

Straightflow says it supports E4 emission compliance only when properly coated with platinum, palladium and rhodium, and that professional welding and the right catalytic coating are needed for full emission function. It is listed for catalytic converter rebuilding, custom exhaust fabrication and emission system repair.

Fitment

This is a universal part, so there is no car list. Check the internal diameter and length of your housing (this core is 130mm x 100mm) before ordering the Straightflow E4 130mm Cat Core.

Straightflow says this substrate needs professional welding and the right catalytic coating to work as a catalytic converter, so plan the job with your installer. If you are asking us about the Straightflow E4 130mm Cat Core, quote the supplier code so we can match the exact item.
