Peter Jones you can most definitely beat the sound of a axle dump diesel. A factory exit 5 or hood stack sounds much better. Axle dumps have to much echo under the bed and in the cab.

Both sound awesome. Kinda like the deeper sound of the 5 inch. I have a 4 on my truck and I love the sound when I get into the higher rpms. Want to do a 5 inch though. And I like the smooth look of the led tail lights better than the stock. The smoked loon is way better then the red but I prefer the led. IMO

I think they both sound great In different ways. Raspy 4 inch. Deep 5 inch. The 4 inch is definitely louder. But smaller exhaust is louder always even on gas pickups if the motor is the same and the exhaust identical besides diameter smaller is always louder. The 5 inch has a nice deep sound if your looking for that

It’s a tough decision though. Lol. Both sound sick

Don't switch, the main difference in the noise is the tune. I have the 5" on my truck and before I tuned it the turbo whistle was louder but then I got the PPEI rumble tune.
@KeystoneOutdoorsman6 жыл бұрын
4 inch has more of a pur whereas 5 inch is a bassy growl. Video only does such much justice though. Very interesting video. This is a common topic amongst cummins owners. "Go big or go home", and "Bigger is better" are oftened chanted around this discussion. I believe 3rd gens sound best with 4" especially matted to a 6 speed. Unless they have the 2nd gen manifold with a large single turbo, like my 04.5 6 speed, then 5 inch is better. Sounds beautiful and one of the loudest trucks in SE PA.
@Downstriker5594 жыл бұрын
Unless you're running 500+ hp 4" is more then enough, you lose some bottom end torque with a 5" in the sub 500s but gain a little top end. It's all on what you use the truck for but imo, 4" is sufficient enough

I like 4inch personally. All depends on what you like but I’ve read several studies and done several tunes with guys that do this all the time and we’ve pretty much discovered that 5inch is overkill on anything less than 800hp. If anything it knocks your numbers down a bit until you hit that hp mark.

It’s silly how people including shops make a big deal about EGR deletes which is not really a big deal. The fine is $5000 but I’ve never heard of anyone getting fined but I’m sure it’s happened. My point is a cop doesn’t know diesels usually and wouldn’t even know where the EGR is if the hood was popped. As far as an inspection you just find a shop that doesn’t care about it

4" does sound great... I personally like the sound of the 5" better and if all you're going for is sound - stick with the 4" and just delete the cat as you said.. But if if you're looking for performance, you'll want the 5" it as it lets the engine breath better and is a horsepower /torque increase up from the 4" exhaust

To those that may not know, Diesel engines operate off of Compression. Although 5 inch Exhaust sounds deeper you will lose lower end torque than with the 4 inch Exhaust. I've had 4 and 5 inch setups and there isn't enough difference between EGT temps to spend more money.
