    I would go for the exhaust that says it is for a 73-88 Blazer, trucks will be different. No clue on what muffler set up, but I need to know too.
    BTW anyone running the 70 series? Are they too quiet?

    Good lord. The rod up that man's butt must have a rod up it's butt.

    Trucks are the same I think, just the kit for a K5 won't have the extension pipes for after the mufflers. I think a center inlet/offset outlet will work for the muffler.

    I'm running flowmaster 70 series. I like em. They are fairly quiet at idle and when going down the freeway. But when you get on it they have the famous Flowmaster roar. I dont think they are too quiet at all. I have got many compliments on how healthy my K5 sounds.

    Heders Re-re-revisted

    Okay it is time for me to order my exhaust setup. As most of you know I have a 2wd. I plan on getting the 50 series Flowmasters 2-1/2, center In/Out. Headers are my main area of concern, I am looking at these two Headman. Can anyone tell me if the Thorley's will work on my 2wd? Are there other Thorley/Headmans I should consider? I am looking at these two because they seem to offer the best headers and allow easy access to ALL the plugs.
    Also what gaskets should I go with?

    Thanks all. Carter

    Have you looked into the Flowtech Afterburner Tri-Ys? I have them on my project Blazer and they seemed to help out with low end torque and high end horsepower. I decided to get the ceramic coated ones, which were more expensive, but they sure look nice. Getting to the spark plugs is cake...

    Check out <a target="_blank" href=http://kliernetwork.net/truckproject>http://kliernetwork.net/truckproject</a> for a few pictures of the headers...

    Not to beat a dead horse, but anyone know if the Thorleys or the Flowtechs will work in a 2wd?

    They will. 2wd/4wd headers are the same thing basically. I've swapped one onto the other. Small blocks anyway.

    Thanks. I finally found the Thorley site, they have another model listed for the 2wd that Summit carries, but does not have on their site. I guess I will be going with these as they are a little more than the other headers I have looked at, and seem to have the best reputation.
    BTW my friend at the muffler shop recommended getting the offset inlet w/ the center outlet for anyone else looking at new mufflers. Now I just need to find some Flowmaster 50 series for a good price, $80 each is the best I have found.
