    Rear exhaust exit VS. turndowns

    Sup men, Im gettin close to droppin in my 350 and running the exaust , im also droppin the truck a lil more and putting on a roll pan. With these modifications im not sure how i want to run my exhaust.I'll be running true duals with two chamber flowmaster 40's and high flow cats. What kind of sound and power does each option put out??? (pipes and tips straight out the back or turndowns) thanks , oh yeah , should I run an X pipe?

    If you got the dough definately spend it on the cross pipes. I've heard many good things about them, heres a link that you can read more about them http://www.kinneysmufflershop.com/x-pipe.htm I would go with the dual exhaust out the back, maybe you could fab something uip to run the tips out the roll pan.

    The perf. difference between straight out the back or turn downs would be wouldn't be noticable. I dont care for turn downs due the fact that they kick up allota dust - more of a prob on dropped trucks. To me, an exhaust system looks more "finished" when it actually goes somewhere (out the back, out the sides, ect.)

    Those flow 40's will sound sweet, but you can expect a helluva lot more noise in the cab!

    some motors need more back preasure than others. when doing turn downs with a bigger sized pipe you lose back preasure.which, on some, hinders performance. the longer the tailpipes, the more back preasure you will have. you will notice power differances if there is not enough back preasure

    Turn 'em down

    Go back to the bumper if you like, but I would turn them down.
    It seems everybody and their brothers let the pipes hang straight out under the bumper.

    If you are going to exit the pipes somewhere don't run them under the roll pan unless you can get them flush, they just don't look as good to me. Anyway it is your choice, but I have Turndowns w/ Flowmaster 40's and no cats and I like them, but they are just too quiet. They have a good deep sound, but mine just don't have the tone that they used to.

    I would definetly say go with the X-pipe if you can...
