This exhaust is made from SUS304 Stainless Steel.  It has 80mm piping where it joins your Y-pipe, and slims to 60.5mm piping where your exhaust splits into dual sections.

The tips are steel as well.  If you want beautiful Titanium tips, you will need to purchase the 5Zigen Spec Street Exhaust we offer instead.

This exhaust is 90db with a stock Y-pipe and stock Downpipes.  With the 5Zigen Y-pipe installed it rows to 103db at wide open throttle!
