Im thinking about purchasing a whole new exhaust set up. New headers, cats, mufflers. I read early there are better flowing mufflers than flowmaster. I like flowmaster but what really is better? And for headers...whats good? Any opinions on ones someone got would be great. And cats, whats the story on them, I want hi flow, any company thats better than the next?

 

The Magnaflow high flow cat seems to be the most popular. Muffler choice is up to you...search online for different sounds and pick your favorite. Anything is better than stock. Headers are a never ending argument over shorty vs. long-tube... Edelbrock makes a nice set of shorties that are direct replacements and bolt right up to the factory y-pipe, too. Check out summitracing.com on those... Search on this forum and you will find loads of info about all of this. Thought I would throw that out there before some butt-munch starts whining about the search feature.

 

If you want a little read on headers to help with HOW to pick the right header here's what I found to help. As soon as I get the cash to start buying a new exhaust I'll be reading over this again to give me a lil heads up on what I pick. http://www.superchevy.com/technical/...der/index.html

I know it's a Super Chevy site but I think headers work the same as far as any motor is concerned.

 

you want a high flow cat for sure , as for the muffler i would go either flowmaster original 40 or cherry bomb extreme headers i would choose edlebrock cerimic coating

 

i dont have headers on my truck but with my experience with headers in general... if your doing a whole new setup i would do long tubes, if you dont like the long tube then go shorty but get the equal length shortys they perform better than regular shorty's. muffler... borla make a damn good muffler, kinda pricey but a good quality and sound with aggresive, mild and mellow choises... i don't know about cats i gutted mine but everything i read points to magnaflow high flow cat. best thing i can tell you and most people would agree is go to you tube and type in what you want to hear and listen... granted its differant from real life and computer speakers but gives you a good idea. good luck with it and send us a clip when you get it done!!

 

here is a clip of what i have gutted cat and original 40's (flows) and 4in tips.

Thanks for the input. I wanted to do headers each header leading to their own hi flow cat. Good idea??? And ive searched all around, found most of the info relative to what you guys are saying, but all the input is helpful. Headers ive never really got into so ill have to look at them. As for muffler, my buddies like the flowmaster series. They sound good. Any thing else someone has to say..let me know whats good. Thanks again

 

I run the ceramic coated pacesetter longtube headers with the matching 3" y-pipe, 3" in/out magnaflow cat, and a 3" in/ 2.5" dual out flowmaster 40 series muffler with 4"x18" exhaust tips. I absolutely love this set-up. Extremely aggressive and bassey, and gurgly when you want it to be. The longtube headers subtracted a little bit of low end, but made every bit of it up in the mid range and upper end for my truck. Personally, I wouldn't even waste my time removing my manifolds unless I was installing longtube headers. In general, exhaust doesn't do THAT much for a truck unless you start opening the engine up. But if you want a mean sounding set-up, that adds a nice boost for your truck overall, then consider the pacesetters, they've treated me well so far, not to mention still look great almost a year later.

 

I'll throw this out here, but this is just my opinion. I'm not a fan of true duals. I just think there highly unecessary unless an engine is packing some serious horsepower. A relatively stock motor will most likely loose power in the lower end with a true dual set-up. On my brothers truck, he runs a true dual, and it makes no noticable difference power wise except maybe getting onto the highway. He used to run a single inlet/dual outlet set-up, and his true dual set-up doesn't appear to have made a difference in horsepower gains. The only thnig it does is make it a pain in the *** to switch mufflers out because he has to buy two lol. This is just my opinion on the subject.

 

You r right here.

Although a true dual can be done with one of those magnaflow mufflers that have the x_pipe built into it.I would not go over a 2 1/2" tubing though.These engines have absolutly no top end so your not gonna gain much here unless you open up the top end,and put in a cam.
