TEGIWA Exhaust Downpipe. The CR-Z came with an unconventional system that cuts out a traditional exhaust manifold, instead the downpipe connects directly to the engine creating a 4-1 system. The Tegiwa CR-Z downpipe comes with a divided bell-mouth down-pipe creating the simulation of a 4-2-1 exhaust manifold. This then connects to a down-pipe which uses a high flow catalyzer. This perfectly crafted downpipe is made from the highest grade 304 stainless steel and is TIG welded. Supplied with new gaskets and bolts.
*Please note that this downpipe removes the first catalytic converter.
