  • Hey, so what exactly did u do to your exhaust? did u change the whole thing? or just from the catback ? it sounds good!

  • @luisxc79 I put short tube headers on. I left the Cats on and ran 2.25" pipe from the cats back to an H-pipe. Then the Flowmasters and pipe all the way to the rear of the truck.

  • @scotts01Z71

    Awesome, ya it sounds awesome.. wHAT benefits are you getting besides sound? how about gas milage and airflow? how much did you spend on all this?

  • @luisxc79 Gas mileage might have gone up 1 or 2 MPG. As far as horsepower it probably went up a few but nothing noticeable. Total cost for everything right around $495.

  • nice truck man

  • @TheBack933 Thank you!!!

see all

  • @derrickmtyma Naw, I like it just the way It sounds... Not to quiet and just loud enough for a good rumble.

  • take the mufflers off and it will sound a hell of a lot better

  • @EJthecountryboyGRAY wonder how much different it would make it sound if i just cut thr pipes off after my flowmaster?

  • @FrisbeeBaller17 Don't be scared,just try it,and if you don't like it,put a muffler on it,at least you will already have your pipe run!

    I will PM you some more info :)
