My EGT probe is post turbo. When I replaced the 3.5" with a 4" the EGT's went down over 100deg while on the highway and in general drop much faster then with the stock 3.5" exhaust. I thought the 4" downpipe was a tight squeeze, but I made it fit.

Try stuffing a 5 inch pipe in there, heard the war stories but for the most part, they'll fit. My 4 inch went in no problem.
Like Alvin said, that is weird, thought the 4 inch system was ALL 4 inch, downpipe back. Unless you got it in parts, subscribing..
Yeah pretty much, they were running a deal about a year ago and I wanted to keep it close to stock, my muffler was getting kinda interesting, so I just got a cheaper system that sounded nice.
Now I would like to actually add the down pipe as I have been sucked into the world of diesel mods.
