4" or 5" exhaust ?

[Smokin 6.0]

Mods are in my sig

I've had both when I had an e99.

5" was slightly deeper. But I switched to 5" when I went s468 route

There will be no performance gain from 4" to 5" with your setup. You will just notice a change in exhaust tone.

I like the sound of 4" with muffler for a daily driver. 5" sounds cool, but you normally get some serious in cab drone.

That's mainly what I was wondering if there was a performance gain or loss

Interesting, the guy who bought my 96 put a 5" on it, and it is definitely quieter in cab than 4" with 2 resonators was, wish I had done it a long time ago. Sounds better too

I have been in 3 or 4 5" exhaust trucks. Straight pipe 5" vs. straight pipe 4" is a big difference to me. In cab drone seems to be much more pronounced on the 5". Maybe the 4" exhaust you had was rubbing somewhere? Or maybe the 4" kits I have experienced are different.

I have both 4" and 5" and have done both straight piped and muffler. My personal prefernce is the 4" with muffler for my DD. My 4" has a 5" tip and my 5" exhaust has a 6" tip. Both are full exhaust, exiting at the rear of the truck. The 5" is noticeably louder and has more of a drone than my 4" which isn't bad in town, but is noticeable on long highway trips.

From my experience, the tip you choose and the exhaust angle/where you dump will change the noise level in the cab as well as muffler/resonator adjusting the drone/sound. Obviously, axle dump or side exit with a 4" may be louder in cab than a full 5".

Very good point here.

I don't believe in axle dumps anyway I don't think they look very good and I hate the thought of soot all over the back of my truck

turndown tips will quiet them down.. i had a 5" dpb on my dually and had a lil drone.. put a turndown on it angled down and back some and you would have thought i put a muffler on it.

it is now a stack in the bed.. lots of drone now.. lol

I've always liked how 4" with a long 6" tip sounded, sounds perfect. High pitched crack at certain RPM's. I hate tips but I'm about to pull my 5" and go back to 4 with a tip. Seems hard to get the perfect sound out of a 7.3

Soot all over the back of the truck from an axle dump? Side exit before or after the tire, definitely had soot issues, but it's never been an issue for me with an axle dump. Always pointed down- they echo off the road more than a straight exit (and closer to the cab making them louder), but I've never had issues with soot all over the truck. :shrug:

I put a 5 inch exhaust on my work truck. The in cab drone is a bit much. Nothing like dual 6 inch stacks on my other truck though. I'll never learn :doh:

If I was to do it again I'd go with a 4 inch.

Ok, who's got the best deals on exhaust systems for a '13? Mike? Someone else?

 

[Cloverleaffarm]

Asking about exhaust prices for your 13'

In the 7.3 section?

In someone else's thread?

Ok thanks

I enjoy being heard .75 mile away with headers and 5" exhaust.

Drone can be rough depending on speed while towing. Just makes the radio volume go up...
