:usflag The future of my truck mods is this: TC, Intercooler, Chip, DP, & exhaust. With my current mods and looking at my future mods, does a 5" exhaust make sense or will a 4" work just fine. I plan to have this truck a very long time and intend to baby it(sorry guys, I resisted, but I did grow up). Just wondering, all things being equal, what difference could I expect to see from a 4-5" exhaust.:thanks:
A 4" exhaust will do you just fine. Unless you plan on going with much bigger injectors and a bigger turbo...there just isn't a reason to go to a 5" exhaust. In fact...without the injectors and turbo...you may lose a little bit on the bottom end by going with a 5" exhaust.
I ended up with 5" by accident, when Tymar sold out of 4" on the day I planned to pick mine up. Dale gave me a good deal on the 5". I suspect that the 5" is responsible for my low torque versus HP (250 hp, 430 tq), but the EGTs are sure low, and I like the throatier sound of the 5". I still like the looks from people who look under my truck and see the huge exhaust

5" sounds so much better then 4" on our 7.3s. i made two identical exhausts one using a 3.5" downpipe and a 4" side pipe, the other with a 4" downpipe and a 5" side pipe the difference in sound quality is big, i did the 5" for asthetics and didnt even expect a difference in sound, but boy was i surprised when i heard the difference.
My 5" is awesome,
pretty quiet though, (sorry muffler, your coming off soon)
my egts dropped quite a bit too!!
