Downpipes are either sold with a set of headers or sold separately if you want an upgraded replacement to the stock.



The most constrictive points in the stock exhaust system are the stock downpipe (to include the u-bend) and the front manifold. The catback is fine as it is. Depending on how far you want to go in modding you could get a downpipe and Plog. If you want to go further than you should get a set of headers.

Here is a link that shows the entire stock 3800 exhaust. Should help you visualize some of these parts:

thanks for the post! pics really help. and just to be sure, PLOG is basically and upgraded manifold, but not as good as headers right? and is the crossover pipe fine as is, or would i need to upgrade that with the headers, cuz the one in that picture doesnt even look right. sorry to keep adding questions, just tryin to learn.

that is correct a PLOG is basically a ported manifold which is a upgrade but not as good as headers, if you get headers they come with the crossover to connect the front and rear, but if you go with a PLOG you have to order one separately although i know some people that get a PLOG and just keep the stock crossover

The crossover is fine if you just want to get a bigger DP and the Plog. Not sure what you think isn't right about the crossover in the pics since they're all the same. There is no upgraded version available (only headers if you want to go that route). I currently have a ceramic coated crossover to help keep the radiated heat down and to keep the exhaust hot as it leaves the engine bay.
