Description

The Modern Performance MPx Downpipe w/ Cat is a replacement exhaust component specifically designed for the 2003-2005 Dodge SRT-4. Constructed from durable 304 stainless steel, this downpipe is offered as a standalone part for those who already have an MPx exhaust system and need a replacement. It will not directly bolt onto a stock exhaust or any other brand of exhaust. If you have a non-MPx exhaust, modifications will be required by a local muffler shop to fit this component. An optional additional oxygen sensor bung can be welded into the downpipe to facilitate the easier installation of an air/fuel ratio gauge. Please note that gaskets are not included with this downpipe and must be purchased separately.
