2006-2011 Honda Civic Si 3" Catback Exhaust for Coupe/Sedan

Featuring a 304 stainless steel piping with 3/8" thick machined flanges this 3" Catback Exhaust for Coupe/Sedan is a great performance exhaust.

The exhaust will still have an aggressive tone and probably never be mistaken for an OEM exhaust, despite the fact that these volume control settings do help to lessen some volume.

Features:

• High-flow performance muffler with straight through design
• 3.5" or 4" muffler tip
• TIG welded to perfection
• Bolts directly to OEM catalytic converter location
• Midpipe available with or without Resonator
