Just installed new twins and have a ?...

[RobertBauer]

I have a 04. 5 600 edge hot juice & stright pipe and my truck was real loud, So I just Installed BD twins and the truck is real quite almost like stock and if it had restricted air flow but it does not feel like it. Is this normal ?

I don't know for sure but you have to realize the exhaust is now going through two turbos and a bunch of crooked plumbing. It's probably acting like a muffler.

The 2nd turbo exhaust wheel is like a muffler. . that's normal

How do you like the hot juice? haven't had one, but thought of trying it.

How do you like the hot juice? haven't had one, but thought of trying it. I think hot juice is great. With the twins I think I should look for something to stack for more power or get the TST & EZ stack. Anyone have any other ideas.

go with the TST and EZ stack its awsome!! your gonna need the transmission done if you do that though! i just got mine done and have been driving it the last two days and i cant beleive the difference in low end and shift points. the transmission must have been slipping pretty bad because now i cant get my TST over 6/5 but before i oculd run 6/6 with no probs on the stock turbo. this of course wont be a problem for you because youve got the twins to keep it cool. get the stack you wont regret it, plus you can get the twins program on the TST.

So I said. . But honey, twins will make the truck more quiet but the look on her face was more of a

I noticed the same thing. As I went to bigger and bigger singles my exhaust got louder and louder. It was to the point of irritating. I picked up a longer muffler that I intended to put on at the same time I did twins, since my exhaust was going to come apart for fitting to the twins anyway. I ended up missing a coupler that I needed for the new muffler and left my old one on in a pinch. The sound with twins totally changed and was much quieter. Lots more whistle through the exhaust and a lot less combustion noise. I think I'm happier with it now than I have ever been.

Yeah I can honestly say that my truck is way louder with the SPS 66 than the stocker.

Twins will definetly quiet your exhaust.

Good info to know for those of us that weigh in additional noise as a consideration in making mods, thanks.



From what everyone is saying, it sounds as though the additional noise in the form of "turbo whine" would be noticed for a larger single and also twins but twins will quiet the exhaust note.
