hey could you tell me exactly what you did I really like this sound and am trying to figure out what to tell the people at the shop what to do

[dkgreyf150]

Its a single in single out magnaflow magnapack dumped with magnaflow hi flow cats

[Pkumar1923]

@dkgreyf150 how much more flow did you get with the hiflow cats? you think

[dkgreyf150]

@Pkumar1923 No power increase but definitely a sound increase. Hope this helps

how were you able to do this with the sensors that are in the factory cats? i have the stock exhaust and just removed the muffler and put a straight pipe in and im lookin to make it louder

[dkgreyf150]

well when i had it done they just didnt put it back in and it pulled the chech engine light but i have a programmer and it made it go away but you can mount the sensor either in front of it or behind it i forgot which one

[mcline86]

okay cool, i have the hypertech power programmer that should work right?

[dkgreyf150]

well if you can i would try to put the o2 sensors back in cause even if your progammer does clear it, it might come back

[1frenchmen7]

did u change the complete catylic system or just the rear cats ?

[dkgreyf150]

i only have 2 cats on my truck stock so i just replaced them 04-05 4 cats 06-08 2 cats

[dkgreyf150]

thanks man but actually i have changed my exhaust since then im working on videos but its a 3"straight pipe its very good sounding and loud

I have a magnaflow 11236 SI/SO on my F150 07 4.6 and it sounds better than trucks in my area with any other performance muffler (GM performance, Flowmaster etc), and some have duals...Mine is perfect...Great bark off the line, and no drone at crusin speeds...but you know its there...NICE TRUCK YOU HAVE THERE MAN!!!...Sounds awesome!

very good sound, especially for a dumped SI/SO. i had a 14inch magnapack dumped for a month or so and it sounded nothing like this.

[dkgreyf150]

thanks darren

[DarrenWS6]

much better sounding, very nice!
