    Thumbs down 4.3L exhaust/muffler poll

    So we are seeing more and more 4.3L's on this board everyday. And of course their modded, why else would you be here. Right? The first thing on the mod list when you get a vehicle is usually exhaust.

    I know I've gone thru a handful of mufflers on my 4.3L; Flowmasters, Magnaflows, Dynomaxs. Hell even today I just cut out a Flowmaster Super 40 for a 3" SI/SO 14"x9"x4" Magnaflow (again) but what brand did you choose? Did you go with a whole cat/Y-pipe back kit or just the muffler? And if you can, post up a vid or sound clip to what you've got.

    Cheers ~Mykk

    my magnaflo is a 3" in and out stainless and i can see right through
    from one end and out the other... it quieter than a stock 2.8 fiero
    at idle and cruise until i hit the loud pedal. Im also running a 3" cat
    as well on a full 3" system.

    I have a set of cheap glasspacks on my s10. I thought it would make it quieter then the opn headers. Not so much.

    I have a 1993 S-10 that used to have dual Purple Hornie glasspacks, !cat and all custom mandrel bent 2.5" tubing. That system actually fell off when my father-in-law was using it. He took it to some other shop and they put a new custom bent 2.5" system on it, but I don't know the brand of mufflers.

    If I had my way, I would have put the Purple Hornies on again.

    I'll post a clip here in a few days.

    Thats like the the one I just put on mine, with a little twist because of the center in / offset out

    Installed the JBA headers yesterday,



    this morning I cut out the Magnaflow, and I've determined that I just dont like them.







    And a new 3" single in / 3" offset single out Flowmaster Super 40 part # 953047.





    And I'll tell ya, the JBA shortie headers, removed cats and single mandrel bent 3" system with the Flowmaster sounds amazing.

    I'll make another one of my famous Exhaust Vids soon. Windows movie maker is acting up on me, I'll need to download and reinstall.

    3 mpg

    I have a muffler elimination pipe with the factory cats on my 2006 Silverado. Runs a TON better, sounds good, and picked up 3 mpg. Even though we have no emission test in MS, it will pass anybodys. It looks stock, with the single pipe exiting behind the right wheel.

    I Got A Cherry Bomb Pro Si/do Muffler Exiting In Front Of The Rear Pass. Tire And I Love It. It Really Sounds Like A V8 Untill 3800 Rpm Or So. I Had A Flowmaster But I Think It Sounded Like Crap On My 4.3
