dude your truck looks just like mine sweet

 

IMHO.. true duals are strickly for all out, high HP, WOT use. Other than a nice sound you will actually lose power on that 4.2. What some guys dont get is that you actually need some backpressure given with a single exhaust system to keep your low end torque. Just an example here. WHen I raced my SS often my friend had an SS doing 10.90's consistently. He had true duals thinking because he was pushing 500 rwhp that was the thing to do. After a year of racing and daily driving he got tired of the resonation and noise so he went with a Y-pipe and catback system. He told me that it felt like he had more on the bottom. Took it to the track to hang out with the guys and did a couple runs and pulled backed up 10.82's. For you guys thats been around racing, it takes a hell of a lot to get a tenth after getting into the 11's.

Oh yeah... I had true duals as well for 4 years then went to a y-pipe catback as well.

Sorry for the rambling got carried away. lol

 

It sounds acceptable for a V6, just don't get too high in the RPM's or else the real sound will come out.

2000th post!

 

Tight bro, stick?

 

yeah it is and it's awesome

 

well it looks like im going to go with the si/do thanks for the help and who makes the best si/do ive herd alot and cant chose.

 

Whatever is 100% straight through and stainless steel, usually is Borla & Magnaflow, but in V6 terms you may prefer the sound of something chambered.

 

I got a si do muffler lastweek and the muff. shop said he'd install the pipes for me for 50 bucks so im going tomorrow to get everything installed in my lil v6, ill post a vid and let you guys give me some input!

 

What ever you choose be sure it's stainless and not aluminized steel... You will pay a little more but they will last...

 

First off you are not going to get a good sound no matter what on a 4.2 its impossible with the even firing motors. My favorite set-up to date on a 4.2 is true duals with and X pipe and Flow 40's. Right now im running a DynoMax Super Turbo with a single 3" system, its not as bad as it was with a glasspack. Look around Youtube a lot of people run glasspacks, there not bad on 4.2's kind of give it a old 2- stroke Diesel sound, but it was not for me, it was way to loud and sounds kind of plan and even, i like the first youtube video i guess its more of a metalic sound i like.

 

your contradicting yourself. Your saying there are no good sounds on a 4.2..and then you say your favorite is this and that..

 

On a 4.2....

 

that sounds good!!

 

yeah i like that set up to one its an si/do and i herd it you straight pipe it you lose power in the end so i'm going to go with the si/do its simple and i shouldn't lose power right

 

The only mufflers that sound decent on 4.2Ls are aluminized steel unfortunately.
