    i just got 2 40 series flowmasters put on my rig and it just has hooker headers. it sounds awesome. i dont know how loud you are going for however but it is deep and LOUD. if your plannin on wheelin hard i would definitally go dumps just because it keeps the water out of your pipes and you dont have to worry bout bangin up those fancy tips that would be stickin out otherwise. heres a pic of mine only a few days old. goodluck though!

    Best mufflers I ever had. Although I have only had Gibson and flowmasters before. These Magnaflows have a really nice sound at idle, really throaty sound when you get on it, and hardly noticable at cruising speeds. Best part is they do not resonate one bit like my flowmasters did. Those things would give me a headache by days end.:(

    Where did you get them, I'm looking at changing my muffler on my 88 and want something that sounds good, but doesn't have the resonating drone like I have now with knock off flows.

    Steve, I got them installed at my local muffler shop. Anyone who carries Flowmaster will likely carry or can get Magnaflows as well.

    Hi Pinion, you are right the flowmasters will rust over time. The Magnaflow are made of 100% stainless steel and while I suppose could possibly rust with age it would take a long time. Heres a link...

    They do make s/s flowmasters, but they are not cheap, but neither are the alumnized ones.

    Here is a link, http://yukon.b0xen.us/headersweb.html, to who I ran my exhaust on my 69 K20. It goes 3" from the headers to the X-pipe. The X-pipe is 3" and necks down on the output side to 2 1/2". Then 2 1/2" pipe back to Dynomax Ultraflo's and on back to right before the trailer hitch.

    I have never used one of their mufflers before but listen to the sound clips. You will be drooling. My favorite of theirs is their new Violator muffler. The clips take a while to load, but they are well worth it.

    Also I am not that much of a fan of Magnifows, but I love Flow Master 40 series.

    I've got them on my '78. How old are yours? can you send me pic's of the flowmasters? I'm looking for some for my '74 trailer queen? Can they be cleaned up? Would you be willing to send the old ones to me after you replace them.....

    The only thing a h pipe does for SBC is make them sound better. May give a little more torque down low but thats about it.
    H pipes are a Ford Winsor thing. They do wonders for winsor engines because of their fireing order. Cyls on the same side fire right after each other. the crossover reduces back pressure on one side flowing excess to the other side with no pressure. SBC has a even fireing order so a crossover is not really needed.
    Running an H pipe wont hurt a SBC but if you have to pay a lot extra for it. its just not worth it.
    To install the Crossover pipe right so it is tuned for your exhaust. The best way is to do the dual exhaust without a crossover. Then spray paint the pipe behind the collector back to the muffs. Take it for a drive then take look at the pipes. The place where the paint starts to burn off is the best place to install the crossover.

    No, those are regular aluminized flowmasters and will look identical to yours in 2 months of winter driving....
    I looked at your mufflers, they have some surface rust on them, but thats about it. Thats what flowmasters look like with a few months of winter driving, I'm sure they would have years of service left in them before they start to leak and actually need replacing.

    flowmaster does have SS mufflers, but they are high. Magnaflow specializes in SS mufflers and systems, but also carry aluminized versions. Personally, I'd go with aluminized. We live in California, we don't need SS because stuff barely rusts here. Try a midwest winter with snow, sleet, ice, and SALT. They are the guys that really need SS. Unless you are building a show truck with super stupid shiny mufflers, I don't see the need for stainless.

    I just put a 5" MBRP system on my Ram Cummins, all aluminized of course, except for the tip.

    Your mufflers are not "rusted to hell." They have normal, standard, muffler surface rust on them that is nearly unavoidable without an SS system.

    Regardless, I can get you what ever mufflers you'd like Jake, just let me know when you are ready. I can help you choose a muffler if you'd like and I can have it drop shipped to your door.;)
