Should you buy THIS GR Corolla CATBACK? (Q&A)

[@3stro]

Ordered mine for Black Friday. Excited to install

[@nikolaiiaksenov]

Best sounding GR Corolla exhaust 🔥🔥

[@ps3jlmp]

Great explanation, is there a number to the slight performance gain from the exhaust in the open valve mode?

[@SoFarFromCrust]

What is the diameter of the exhaust and downpipe and will they pass emissions

[@ricastar2931]

Does anyone know if it’s compatible with a versus rear diffuser that’s the only thing that is stopping me from buying it
