Thread: Exhaust Ideas

  1. #1

    Default Exhaust Ideas

    I was thinking about pulling the trigger on a single in dual out flowmaster muffler. I was gonna y-pipe it into the stock exhaust pipe with a nice tip or should I just get a single in single out flowmaster muffler. I would think I would get a better rumble with the single in dual out and the y-pipe, but I'm not quite sure.

    I have a Dual in Dual out flomaster 40 series with a x pipe sounds deep and really good! I had straights that were loud but they dont sound nearly as good as this does! I'm thinking about taking flowmaster off and just running x pipe with straights it will make the tone deeper along with having big tips also.. i would go with the dual in dual out setup witha x pipe. has them they are the magnaflow tru x pipe already welded ready to go for around $85.

    I was going to run the single in dual out with the Magnaflow y-pipe, stock pipe, and Gibson tip for now. Maybe somewhere down the road I will look into that though..

    Yeah man that setup cost me some money but is worth it!

    If you want a rumble, do a SI/SO flowmaster Super 44. My brother has those on his P71 crown vic with a 4.6 v8, and it rumbles great. That's just my .02

    im running a single in dual out flowmaster super 40 (see the sig)

    sounds great, and as long as you dont really rip on it sitting still, no crackle whatsoever.

    just a nice deep, even tone.

    go into my profile and into my photo album for a good pic of my tips. there 3 inch ID double walled. 18 long.

    this whole setup was 480 installed. not cheap but totally worth it.

    The reason why I was going to run a single in dual out with a magnaflow y-pipe is to get a nice rumble for now and then down the road when I can afford it is get custom made pipes to make it sound really good.

    I agree, after all, it is YOUR truck, not ours

    I was just wondering if it would sound good. I am probably gonna get the super 44 muffler.
