Description
Borla S-Type XR-1 Cat-Back Exhaust is built for 2004–2007 Subaru STI. The tubing layout is 3".
Sound and Engineering
S-Type tuning adds a more pronounced exhaust note with a balanced performance character. Cabin resonance and outside volume are different characteristics, and the complete exhaust configuration affects both.
Mandrel-bent tubing maintains its cross-section through bends, keeping the intended pipe shape through changes in direction.
