Welcome to WeldAffection — brilliantly designed by taking the best assets of our original Downpipes and adding new design features. We have achieved the ultimate goal: performance.

These Cat Bypass Pipes will make your G30 sound very aggressive, while also providing faster spool and an increase in power.
