stock internals? lol. yes with stock pistons you want 2 1/4 not 2 1/2.[sm=bangbang.gif]

go with a 2 1/2 inch. you are going to want to do a bit more to your truck down the road. 2 1/2 is perfect. 3 inch is OVERKILL. 2 1/4 is OK, but the 2.5 is the perfect size.

don't both with those mufflers with an x pipe in them either. you want a dual system, not a marketing toy.

 

But i dont want to pay a whole lot... I dont plan on upgrading my engine or anything i just want a good deep louder sound. And i think by getting new pipes bent properly and a muffler change with long tips then i think ill get the sound i want.

 

I would suggest using 2 1/4" or 2 1/2" piping and going with an h-pipe/x-pipe with 2 mufflers. That's the setup I have along with the Flowmaster Super 44's and I am really happy with it. Or you could just do a si/do system, but I think going the other route would be much better, imho.

 

well i dont plan on doing much with the engine. Im just looking for a good sound thats cheap enough.

 

i agree. your opinion is not only your opinion, it is the truth.

bottom line: ur not going to find specific prices here, like i said before, go to a reputable shop that specializes in exhaust work.

as far as cheap is concerned, refer to my signature.

 

I dont mean cheap like that... I just dont have 500-700 bucks to throw around for an exhaust. But again ill have to find the best price.

 

If you want it louder, just take out your old muffler and replace it with a Flowmaster, Magnaflow, Dynomax, or any other random brand highflow muffler.

One thing to keep in mind though. If you want to avoid choking out your motor with backpressure, your going to need at least 2.2 cfm of flow per every 1 Hp your engine produces.

2.2cfm supports a maximum of 1 HP.

If your planning on building your motor, just make sure that your muffler, cats and pipes will be able to support it all.

Calculate that you have 235 base HP at the crank, thus you need at least 2.2 Cfm per 1 Hp.

2.2CFM X 235HP = 517cfm requirement of flow from your exhaust system to prevent any loss of power from backpressure.

 

I work at an exhaust shop and i can tell you pipe size dose make a diffrence, yes the majority of the sound diffrence comes from your muffler but bigger pipe will make bigger sound on my truck im running 2 3"in 3" out flowmaster 40 series a 3" mandrel bent tails no converter to only thing not 3" is my Crossover pipe. i would definatly not reccomend 2" pipe most of these trucks come with 21/4 from the factory so even with a high flow muffler u will be restricting your exhaust flow. there are a ton of exhaust options for these trucks and ive done most of them on my own truck just trying to decide what i like best. if you go with a common single in duall out set up it would bento hard to change out mufflers down the road if you dont like the sound. it all comes down to how loud you want it and what u are willing to spend,

 

Blkbaretta hit it right on the head. If your going to do that true dual, 2.25" or 2.50" piping is the way to go. Either way I think you will be fine. Save some money up, and get it done right too. There is no point in short changing a project just because you are anxtious, trust me, I know this for sure. I run a si/do system right now. It is VERY loud, in fact, one of the best sounding trucks I know of. BUT, if I could do it again, I would have gotten a true dual, especially now since I have headers, and will be soon purchasing a fastman tb and intake system. If you don't plan to go crazy on the truck in the future, I think 2.25" would make sense then, this way you won't have to compromise much of anything. If you do plan to get an intake system and a fastman however, even if its way down the road, then I think 2.50" is the way to go.
