Come with:

OE-style Heat Shielding with ceramic inner liner - signature DTM-Tuning thermal management feature that reduces radiant heat from the exhaust pipes up to 70-80%. Being inspired by racecar engineers who uses it alot, we moved heat shielding to the tuning industry and made it available as an option for any DTM-Tuning products. Usual thermal wraps or ceramic coatings are not even close in effectiveness and durability to our Heat Shielding. Please be aware of fake shielding when it is nothing but foil wrapped around the pipe. Without a sufficient ceramic wool layer inside and properly embossed foil it will not work as expected.

Straight Tunable 02 Spacers - Comes with 3 inserts to restrict flow to the 02 sensor and help set ready and prevent Engine Light conditions when using the Competition model without proper tuning.
