OK. I'm going to eventually do an exhaust on my truck, but I searched and didn't come up with any results I was looking for. I know I want duals like the lightning style in front of the rear tire, but would it be beneficial to truck performance to make it a true dual setup? Are true duals really all that louder? I haven't had the experience with exhaust on trucks or v8's so I am hoping to learn from you guys' experiences. Thanks in advance.

 

I'm not positive, but I don't think true duals are all that much louder. And unless you're building a race car they probably aren't necessary. Plus the added cost of having to buy another muffler... I'd just do SIDO.

 

True duals should flow better for better performance . My mustang had duals so I do think there is a performance advantage over a singles splitting into two pipes

 

True duals=Performance, it's a truck lol not meant for high flying speeds! I'd get si/do if you want the loudest muffler si/do try IMCO at www.grabthepower.com they have single chamber si/do and it's the loudest muffler that I know about!!

 

I'm not looking for loudness, but since I'm going to have an exhaust made, figured a true dual setup would be better. Never tried this before, so keep em coming.

 

I'm getting flowmaster orginal 40..

 

Okay your considering True Duals, but your going to keep your cats correct?

I've talked with a few exhaust shops before I got my set-up and said they wouldn't take cats off and it basically would be the same sound wether you have one or two mufflers.

 

Well i think i can tell ya what you want. I had a thread going a few weeks ago but ill start all over.

I got my truck dualed out at the exaust shop and he ended up doing a true dual from the cats back. He ran 2.5'' pipe back after cutting the factory Y pipe off. So it was a true dual with the cats and NO muffler....It was loud, very loud but sounded good. Had alot of kackle but it was real mean.

After a while of that i decided to put a muffler on so i wouldnt wake up half the neighborhood when i got on it. So i bought a DI/DO Magnaflow muffler and had them install it. It seemed quiet at first until i got used to the change of sound. I LOVE the sound now. It has a built in X pipe which gives it a very distinctive sound. I think you would be satisfied. Any questions feel free to ask...

 

Hey trytokeepup, thanks form the info. That's just about what I was trying to find out. Anyway, how is the sound in the cab? I know the style I'm looking to do is lightning out the side and figured true duals would be better and less restrictive. I have looked at different mufflers and have seen the type you have installed. I am eventually going to have this done. I can't wait!

 

At cruising speeds cant hear it too much. Thats one of the main reasons i got the muffer. It doesnt drone or anything. I really only hear it when i start to crawl up hills and it pulls the engine down a bit. But its very tolerable. Sounds great when i get on it inside the cab. I havnt heard it yet from outside since the muffler but im hoping to find some trustworthy person to drive it haha.

 

Give me the keys..............

HAHAHAHA Should i send them UPS or Fed Ex?

Tom whats up? Im on one of my hour breaks between classes. Just started back today. Man one more semester of hell. Anyways i have about 10 minutes to get to class. Cya later Tommy.

 

thats nice man. i kinda wanna go with that same setup.. cut off the y pipe huh.. hhmm.. i was thinking si/do and dump it before the back akle, but i want to keep some sort of backpressure... did you feel any gains??..

chris...

 

Hi.

Actually, you want to preserve exhaust gas velocity and effective cylinder scavenging. Backpressure is not a consideration in preserving low-end torque while enable an increase in midrange/topend power.

If you spend some time researching this via Search, you'll see what I'm referring to. There is a lot of BS mingled in with th facts, but one thing stands out: true duals look great & can sound awesome, but be prepared to suffer some loss in low end; some notice it more than others. And yes - mandrel-bent/constant diameter pipes are a must.

Cheers

Actually i didnt notice any loss at all. Didnt feel much of a gain but its exhaust. So you loose or gain 5 horsepower....you wont feel that. Heck after i got the muffler on i had my truck reflashed just to get the latest updates and it runs like a rocket now. I havnt noticed any low end loss. It lays just as long as black marks as it did before.
