ETS '22+ Subaru WRX Single Exit Catback Conversion

This rear-section conversion turns an existing ETS VB WRX catback into a single-exit system with a 4-inch tip. I'd choose it for the single-exit appearance and simpler rear layout while reusing the ETS midpipe already on the car.

Stainless steel keeps the cost down; titanium reduces weight and gives you the brushed or anodized finish. Requires a compatible ETS catback midpipe. This is the conversion section, so you still need that midpipe to complete the exhaust.
