thanks...it sounds nice but i may have to add another small muffler...it doesnt resonate thanks to the resonator, but its loud, i imagine towing will suck. Thankfully I have plenty of 4" mufflers laying around to play with.

 

Post another vid once you figure out which muffler. I would like to hear it again!!! Sounds great though.

 

Do you have a before vid by chance?

What was the reason for this swap? Is it just for a better sound or was it for power/economy or something else?

 

before with the 3rd gen manifold? I have a few...with a 51" Donaldson and one with a short straight through muffler...


The reason i did this swap was to go to a slightly larger turbo and a free flowing exhaust side. I am hoping that it helps my fuel mileage...before i was running 10-20 lbs of boost cruising at 70-80 mph on flat ground...i havent had much chance to test so far but it is alot less. I swapped a 2nd gen manifold on just for even flow and the nice sound....since i was digging into it...

 

4" with 51" donaldson...stock programming 3rd gen manifold...before cam swap

 

This was right after i bought the truck in april 2007...no cat with a small 4" straight through muffler...i couldnt stand this after towing one time....this was when i had a smarty...it was set on 90

 

question for you all!!

MY smarty Jr. Obviously does "boost fooling" but i drove my truck to work this morning with stock fueling...and it threw and overboost code on stock fueling...is there a homemade boost fooler i can make myself? some sort or resistor? Right now i have the stock sensor from my stock turbo plugged in and ziptied up. I cant see spending 100 bucks for a little connector from quadzilla?

 

where is the best place to get a "wastegate fooler"?

I know Industrial Injection, or just about any turbo vendor will sell you the wastegate pigtail.

 

Man I need to get one of those manifolds!! Sounds great.

 

That truck sounds so much freaking better than the stock 3rd gen manifold, heck of a good job with the switch also Levi, I like it alot.

 

Thank you veyr much...it seems like it is a littler spuinkier sounding than 12v's and 24v's....but it Definitely lost the nasty 3rd gen ricer sound..it has the inline 6 diesel growl...reminds me alot of my striaght piped c-12

 

sound nice im going to do the same mod by summer.

 

I wonder if my helix 2 helped with the exhaust note as well?

 

I am new to HPCR motors...what is a helix 2?
