Have you guys seen this? This guy claims to have "true Duals" on the LS4. How???!!? People ask him how did he fab this up & he'll just give short answers. I'm thinking this guy may just have a cut out LOL!!

Check it out:

flag for that.....I pretty sure that there is no room for real TDs.

 

I agree Nacho!! Did you read his answers!! man!! so short & suspicious!

 

I am sure there are several different manifolds that "could" fit, but how do you get the single pre cat and post cat O2 sensors to work on a duel manifold system?
The lack of room under the car is one thing, but the electrical system change is totally different.
Any LSx manifold could work to convert it over to a true duel system, but adding the extra two O2 sensors will be a challenge.

 

LOL ya guys that is me actually asking how in the f*ck he did that. I call bs

 

I read your reply on this link!!

I can't wait to see what this guy has to say!!

 

07carlocrusader,
He could of put the 02 simulators but I raise the flag also!!

 

LOL its funny how you think he has a cut out because my cut out open sounds nothing like that

Yeah I commented on that video too and I'm a little dumbfounded because the exhaust exits on one side and there is no room to run true duals thru there and down to the underside of the car. Sure duals are do-able after the down pipe, but then you just make a giant y-pipe.

 

yeah Its time for me to ask what the hell is going on here, he even answered back to someone and said:

I used to have a full magnaflow exhaust (headers back) like everyone else... I didn't want to have the same thing, that everyone had already done. So I had gotton rid of that crappy Y pipe, and had someone fabricate straight pipes from the headers back. Less bends in a pipe, the better right? Yes, it is loud, but it sounds good.

Header's back?!
LOL!!
Does this guy knows what he's talking bout here??

 

Probably BS'ing, however I don't get caught up with the random crap that people post on Youtube. And cardomain, there's alot of crap posted there. There's a guy there who claims to have a rear mount STS turbo kit on his Imp SS, however only has a real tiny pic and is always very vague when asked for details. Plenty of these nuts who have nothing better to do then say they have things they don't actually have.

BTW, have you guys seen my turbocharged AND supercharged LS4? haha

 

LOL!! I seen it!! Have you seen my friend's rear drive 2011 Monte Carlo SS!!?? He had it since January of last year!! LMAO!!

But Seriously, I agree, I just hate when you thought someone has made a breakthrough & their just shootin-the-**** wit ya!

 

Sounds like a cutout with rev limiter removed to me.... in a garage that has alot of sound bouncing off walls.

 

Sounds like my GXP when it had 3” catless dp 3” slp resonator & 2 3” magnaflows. I disagree there is plenty of room for duel 2” pipes under there.

 

I hate when people record sound files in a hollow room like a garage. Its makes the quality too muddy.

 

Maybe I am really optimistic, but I hope this guy was able to fab up some true-duals. If he really did, he needs to how some pics of the underbody.

 

I'm trying to work out the math mentally, and I'm honestly not sure if true duals would offer and kind of performance benefit. What I'm thinking is this:

With true duals you have two narrower pipes coming back off the engine, so where you have bends, you'll get more air resistance. Air moves slower along the sides of any kind of pope because it comes in contact with the sides, so with two smaller pipes you increase the friction as compared to one giant pipe with a lot of room in the middle.

On a more tradition RWD true duals make sense because uou don't have to sacrifice pipe size, whereas with our transverse mounted engine, I'd imagine you'd need to use smaller pipes to fit in there, so all you're doing is harming the rate of flow of your exhausts.


Or am I totally messing it up in my head?

 

I looked at the video again and found that debris fell under the car about in the middle of the video center of rear and a gust of air when he revved it blew the debris not from the muffler he has a cutout no doubt!!

 

Damn I was looking at that the first couple of times I was surveying the vid myself! I seen that trash or paper towards the back but I didn't see any exhaust mist, tips weren't flexing or anything like that. Once you fab up a job like this, (if its true)wouldn't you most certainly see pipe flexing?? Due to the lack of hanger mounting locations for true duals on our cars, particularly!? Unless the muffler man is some type of God.....

 

You know it He has a cut out!! Sounds good though.
