Down Pipe

[Chiller]

Does anyone know if any 4inch down pipe will attach to a 4inch mbrp dual system? Im asking because I know mbrp does not make a 4inch downpipe

Thanks

yeah it should 4in is 4in as far as i know

yes it will... but the 4" downpipe rubs and cause exhaust leaks which causes exhaust to get into the cab.... stick with the stockdownpipe

I was just wondering if different companies make different flanges

they all should interchange (for the most part)

Here's the difference between the stock 05 down pipe and a 4". The 4" fits but takes careful adjutment so it doesn't rub the up-pipe or vibrate against the firewall.

how much louder does the 4" make the truck?

Well if it is a 4" with no cat and no muffler it is quite a bit louder, especially at WOT. At cruising it isn't all that loud. I like my staight pipe setup.
