3/8" thick machined flanges

Options:

3" Catless

Replaces both OEM top and bottom sections (each houses an OEM catalytic converter) with full 3" straight piping.

3" Catless with Resonator

Like our Catless Downpipe, completely straight through flow but with an added Resonator to help reduce drone and overall exhaust volume. A great option for those that want all the performance, but don't want to wake the neighbors!

3" High-Flow Cat Downpipe (Ceramic OR Metal)

For those that feel they must run a catalytic converter. We replace both OEM cats with a single high flowing 3" cat. Ceramic Core efficient to 450hp. Metal Substrate Core for those making 450+hp.

3" High-Flow Cat Downpipe with Resonator (Ceramic/Metal)

The most low key variation we offer. Full 3" design, with both the High-Flow Cat and Resonator options.

Wideband Option

A pre-welded O2 sensor bung with plug for a future wideband sensor install.
