Throaty, Spooly 2nd gen

[joecool911]

Yesterday I heard a 2nd get start in a parking lot. Very throaty and the turbo spool up was also very obvious at start and idle. Is this possible with just exhaust work or is this a turbo upgrade too?

[Me78569]

likely turbo.  

 

I know my VGT starts pretty "spooly" as it walks from idle position to warmup position.

I'd say it all depends. Here's mine with just BHAF and 4in tbe and I think it sounds fairly 'spooly' for just those mods.

I'm running factory 3" with a straight flow muffler and mine is also very spooly sounding as well and can be heard again decelerating get a nice unspool sounds too..

Mike do you get any cab drone?

[joecool911]

Thanks guys. Might start with Diamond Eye 4" without muffler and go from there.ncan always add a muffler later if my wife decides it's too loud.?

[Me78569]

I never understood the drone thing.  I have a cheap 4" straight pipe and really all you ever hear is injection and induction noise, at least when cruising.

Same here, although I feel the more I felt I listened for it, the more I thought it was there. But if I just was driving and enjoying the sounds, it wasn't a bother. It does get fairly loud at highway speeds but not terrible unless under decent loud or grade.

That's what exactly the way I approached adding mine. Figured I'd start straight and add a can later if I wanted. Doing it the other way around is a little harder. You won't be disappointed with a DE that's for sure.

I done a Diamond Eye 4" on a 1995 Dodge turned out awesome with muffler. The Diamond Eye muffler is a straight through like mine is and its still got a bit of noise but no drone and nice cruising with.

My dad did the same thing with his 96 and the drone in the cab was horrible. It was giving us both headaches, so he stuffed another muffler on it. The same thing happened with my brother's CR. 4" exhaust, and droned horribly! The 24Vs don't seem to be as bad. Mine didn't have much even with a straight pipe and aftermarket turbo.

Only if you have full length 3" or 4" exhaust system. If the exhaust pipe is shorten or dumps early or under the truck is still going to drone. Bigger the exhaust pipe the more chance of drone.

There goes my dream of a 10" exhaust system?

[Me78569]

If you build it they will come.

 

 

 

wait no wrong advice.

Let me know Joe if you don't like it, I need some more culvert for my driveway.

See the 12V had the stock turbo, then a 3-4" down pipe, then a 4" diamond eye muffler, then exited the stock location. It's an eclb as well. Idk why it did what it did but it was unbearable!

My brother's 05 got MUCH worse when he went from a stock he351 to a phatshaft 62/65/14. After he put twins on though all drone is gone.

[notlimah]

So you're saying the cure to in cab drone is putting on twins!?!?

I'll let the wife know!!!

I used to run a straight piped stock exhaust.  The truck acquired a drone when towing above 2000 RPM until I strapped a T post to the section of exhaust where the muffler and resonator were originally mounted which reduced the drone to almost nothing.  Overall sound was nice but tended to be a little sharp and rappy, especially when accelerating hard with a load.

 

I now have a straight pipe 4" system and when installing it I specifically used all the available mounts and hangers so as to keep the pipe taught, movement free, and exit in the same stock manner.  Because the common reason for exhaust droning is not only the reverberation of exhaust waves traveling through the pipe without interference or obstruction but when the exhaust pipe is allowed to hum like a guitar string from lack of support.

 

Also, this 4" exhaust sounds much deeper and throatier and sounds more mellow too.  And even though there is no muffler, its not that loud either unless I'm on the throttle hard, then you know I'm there.

 

I also blanketed about 6 feet of the pipe beside the transmission to stop radiant exhaust heat from heating up the transmission and transfer case, so I cant say if that material did much of anything to reduce noise.

[notlimah]

That's a good idea on the wrap, what did you use?

[joecool911]

So a culvert pipe and tee post is all I need?
