Opinions on exhaust please

[Nor_Cal96]

So.. back in june i bought my truck and just recently started lookin into my exhaust. Its hard to decide what to do there are honestly no OBS 7.3s around here with exhaust so idk what sounds good or not. I'm Basically looking for a deep loud exhaust.. i've heard 5" or 4" but i'm not gonna run stacks just gonna route it like the stock exhaust idk... any suggestions and opinions would be greatly appreciated. thanks

I just installed a 4 in MBRP, turbo back, cat delete system on my 97 7.3. It sounds good, but I was looking more to open up the exhaust system because of the extra fuel burning when I installed my chip. I wasn't really looking for a deep sound, just performance, but it does sound better than the stock system and breathes a whole lot better. I've heard the 5 inch on other 7.3's and it sounds a little deeper to me. I am happy with my 4 though.

+1 on the MBRP system.
I'm running a 4" system to 5" tip on my truck with the cat delete. Sounds great. Looks great. No complaints.
Thinking about deleting the muffler here in a couple weeks.

The Diamond Eye exhaust systems seem to be holding up very well. They are inexpensive as well.

a 5" kit isnt needed, it wont provide anything except a small exhaust note change.

Paul @ Complete Performance can hook you up with anything you need.

Ill be going with the 5" Diamond Eye on my truck when the time comes.

Hi,
I just put on a diamond eye exhaust this week. It does require some cutting and the bending of the fire wall weld. It takes patience and tools. The spare tire will need to be adjusted.
As stated already pretty good value.
FYI i installed a 3" down pipe and 4" exhaust not straight piped re used the stock converter not sure of correct name for it on a diesel.

I have 5" and it has a really deep sound, I love it. Then on my dad's truck we have a 4" Diamond Eye with a muffler and no cat since it is a work truck and it is actually really quiet. I really prefer the 5" though, you can really hear the turbo whistle with it. The only downfall with 5" is that it is a little loud in the cab, not too bad though.

5" is a sweet deep whistle, 4" is the same, just not as deep

Thanks for all the info i think i'll probably end up with a 5" just for the simple fact that i am looking for that deeper tone and my turbo and injectors as well as a few other performance mods are in the near future anyways i'm sure nothing crazy enough for 5" but oh well we'll see how it goes haha

Just want to point out the 4" MBRP kit I'm running let me leave my 35" spare in the stock location. Something to think about when considering the diamond eye, as relocating a spare can be a PITA.
