    I would appreciate some recommendations regarding exhaust setup. I have just completed my 350 TBI installation, using Doug Thorley headers w/three inch collectors. Two into one for single, dual, or dual w/crossover? Flowmaster? I want to get your opinions and any information on dyno proven setups. My project truck is a 1973 fullsize.

    do you need to run a catilytic converter? if not then run straight pipe down past the t-case then an h-pipe for some good sound then i would put on a pair of magnaflow glasspacks with some stainless tips at the back of your rig.

    Exhaust

    No Cat, 1973 is smog exempt. By H, do you mean dual w/crossover?

    that the setup im likely to do, cept maybe 3". im gonna go with the new flowmaster super 40s, which are suposidly louder and give a lil more hp then the original 40s.

    I voted for the single set-up. I would go with 3" tubing. The single set-up is less weight, performs well, and as Z3PR stated, less chance of it getting hung up on something.

    i said dual...its what i have on my truck, everything is tucked up in the frame rails and stuff...no way to get it hung up on anything IMO. Simple and easy to do, no Y pipe to get hung up, no x pipe to complicate stuff, simple and straight back to 2 superturbos dumped over the axle. So far it works well for me. Im not worried about sound much and im happy with these quiet super turbos.

    duals are kinda cool in that they are simple and tend to offer better clearance (no need to worry about where the y-pipe crosses over!) but not so cool if you want to run a clocked doubler. I would think the 205 and the passanger-side exhaust pipe would be occupying the same place... could be wrong though. Anyone have duals + a clocked doubler?

    Hey guys post some pics of your exaust setups! I would love to see how you routed the tubes for an H pipe or single exaust.

    run a single croosover, no x pipe, its easier and sounds better, magnaflows flow better but flowmasters sound better, maybe a few horsepower differance, (2-3) thats why i went with flowmasters, they just sound better. i worked in a muffler shop one summer and if was all out power then it was magnaflow but if it was sound it was alway flowmaster....

    hmmmm...i could see that being a problem, but for the majority of guys on here, i feel duals would work well. I don't ever see myself running a clocked doubler (maybe clocked single case, but kinda doubtin that too at this stage in my life) and will prob keep what i have for a while now.

    Hello,
    Dude go with the dual with the crossover. I did a whole new custom exhaust for my K5 it was easy. I ran shorty headers with cats then a H-pipe then flowmaster 40's. I ran the exhaust right out the back. When I kinda get on it it sounds like my truck is a race car. When I really get on it sounds like I am pushing 2000HP. I mean it sounds GOOOOOOOOOOOOOOOOOOOOOOD.
    The only place where I am scared that my exhaust will get ripped off is where I bent the pipe coming off from the headers. The bottom of the bend is alsmot even with the bottom of my diff :doah: . I will be changing that soon.
    Thanks
    Adam

    The Powersticks sound awesome but are as loud as straight pipe. Back when I was dealing with smog, I ran a 383 with headers into 3" pipe with 3" cat and 3" Flow 40 series. The Super 40's are little deeper, and dont seam quite as loud as idle. I like em cuz they make more power and are deeper. Right now I am runing dual 2.5" with Flowmaster 40's and the Powersticks right behind 'em. If your gonna run a Flowmaster or other chambered muffler go with H-Pipe behind tranny. If your using a straight through muffler use a 'X' Pipe. On mine, I get the deep sound from the Flows, a little bit of dragster crackle from the Powersticks and a nice whine from the gear drive on my 425-450HP 383!! All making it difficult to hear that 12" sub I just put behind the seat...

    super 40s

    Like trial blazer said, the Super 40s are a deeper tone with way less interior noise, But they still sound Awsome. Until I recently sold my 71 4wd I had two trcks to compare. My 71 Chevy 4wd short bed had a 396 with flowmasters with dual 3inch exhaust exiting out the sides behind the tires. I don't know what series flowmasters they were. They were on it when I bought it. It sounded awsome, but you had to raise your voice to talk in it driving at 55. My 70 Chevy 2wd, also with a short bed and 396, had dual 3 inch exhaust with super 40s and it also sounds awsome. It has a deeper tone but really screams like a flowmaster should when you get on it. you can drive down the intersate turning 3000 and still talk in a normal voice and it has turn downs about 18 inches behind the cab! I love the super 40s. :burb: :usaflag:
