April 29, 2004New to the street truck scene. Own a 02 Dodge Ram. I already installed a K&N intake and got a taste of a little power. I wanna add a little more. I dont know what to go with next, headers or a Cat back system... can anybody out there help me out?

April 29, 2004put a full new dual system on with headers, high flow cats and then your choice of mufflers
April 30, 2004Personally I`d work on the back end of the system first. I`ve seen a few posts on another site where an owner got some good gains with straight pipes via cutouts bypassing the cats.
I`m not suggesting you bypass the cats, but with his gains it seems the stock manifolds will support a lot more flow than the back end of the system will.
April 30, 2004If money is not too much of an issue go with headers and a custom exaust from a reputable shop in your area. If you`re on a budget the cat-back is definately the way to get started. Also ask the local hot rodder/car builders for resources and opinions, they will know where and where not to go for quality work. One more thing, if you do go with headers I recomend you invest in some "stage8" locking header bolts Stage8 They are worth every penny since regular header bolts can work loose repeatedly over time.
May 3, 2004Ok, decided to go with a cat back.... now one more question, would just replacing the muffler have the same effect as a full cat back? Or is installing the whole system better? What do you guys recommend? I`ve been reading up on the American Thunder system by Flowmaster. Any good?
May 3, 2004its be a hole lot cheaper to just replace the muffler
May 3, 2004Doing just the muff will help, but most cat backs offer bigger tubing and mandrel bends as well. I`d suggest at least bumping up the tubing size from the muffler back to reduce restriction.
The majority of single systems I`ve seen for small blocks use 3" pipe from the muff back.
Haven`t seen anything specific about the American Thunder on a Hemi, but if I recall correctly saw mention of a Gibson that the owner seemed pleased with.
May 3, 2004holy ****in ****.....
the magnaflow catback on the new hemi dodge was the baddest thing i`ve heard....
definetly putting one of those Magnaflow dual exit mufflers on my next rig!! the sell for about $95 and i`d run 3" out to 2.5" with pipes either custom bent or maybe theres a kit out there.

quote:Personally, I think anything by Flowmaster is garbage, for the most part. Anything that is made by Flowmaster can be found made by someone else that produces better results for about the same price. Sounds wise, sure the Flowmasters sound awesome. American Thunder/Force 2 systems are over played. All they are, are regular Flowmaster muffler with mandrel bent pipes. All you do is get the same Flowmaster muffler used in the American Thunder set (in your case a 50 Series SUV) and have a reputable shop bend you up some mandrel bent pipes. Wha-lah. American Thunder. Cheaper than the Flowmaster cat-back? Idk...that depends on the prices of your muffler shop.

If you`re looking into more than just sound, take a look at other than just Flowmaster. I recommend Dynatech if you have the cash to throw around as they don`t come cheap. For the about the same price as a Flowmaster, Magnaflow comes in at the top of my list. Straight-thru design so you get maximum flow as compared to the "Slowmasters".
More cat-backs to look into would be from the likes of Bassani, Borla, Dynomax (I don`t think they offer cat-backs, but they do have full exhaust systems), Edelbrock, Magnaflow, and I`m sure there`s a few others I forgot.
Muffler wise, there`s a plethora of them out there that are better than Flowmaster. Hooker Aerochambers/Max(imum)flows, Magnaflows, Dynatech, Dynomax UltraFlo, Borla XR1 (unsure of their turbo mufflers), Edelbrock mufflers, Spintech, along with many many others.
May 4, 2004has anyone here had a muffler shop custom bend dual pipes from the muffler back??
it seems like it wouldnt take very long to put them thru into a mandrel bender but i have never seen the entire process carried out.
would i longer muffler case make a difference in loudness and sound? i see 18" and 22" cases and wonder what would be best for a stock 350 that creates the best sound.
May 4, 2004flowmaster makes a tail pipe kit thats a good deal and kinda custom you put it together they way you want it.
if i had the cash id go dual into a 70 serios flowamster running a 3" single tail pipe.
then ad the bassani headers later
one of the best exhaust`s for small black v-8s is 3" single from the headers or crossover back.
dual inot a single would produce for flow becase you could go with 2.5" pipe instead of the the restrictive crossover pipe.
lots off exhaust stuff here
heres that flowmaster tail pipe kit
