Have a MPx exhaust on your 2003-2005 Dodge SRT-4 and want to buy a replacement downpipe?

We are now offering the MPx downpipes sold separately from our exhausts in this listing. This is the same MPx downpipe we package with our complete exhausts and these are made with 304 stainless steel.

This listing is for the downpipe with cat for use ONLY with the 2003-2005 Dodge SRT-4 MPx exhaust system.

We offer an option with this downpipe to have an additional oxygen sensor bung welded into the downpipe to make installation of a air/fuel ratio gauge easier. If you dont plan on adding a air/fuel ratio gauge soon, or dont have one installed in your car now, theres no need for this option.

Please note, this does not come with gaskets, so please purchase gaskets in our seperate part listing if you need new gaskets)

This downpipe is only designed to work with MPx exhausts, and if you have a stock exhaust system, or any other brand of exhaust, this will not bolt on. You will need to have a local muffler shop cut the flange off, and weld/modify this to work with whatever you have.
