heres a pic of one of the cats
this is by far the best exhaust mod ive done i dont suggest you do this unless you want a craaaazy loud exhaust my whole floor shakes and i cant talk over it when i floor it ima try and get a sound clip soon ive been so busy

 

Awesome man congrats.

 

cant wait to hear it! what else you have done to exhaust?

 

Travis,

I see you have an 05 F150 as well. What is the exact Magnaflow part # you used that fits our trucks? Are both of the cats the same models? I'm trying to figure out which ones to use for the O2 sensors on the 05 truck.

Thanks!

Will

 

How hard was the install, i have a magnaflow 18in catback, with a volant and its not loud at all, how much were they.

 

It sounds like you like it, congrats.... I agree with it being the best exhaust mod, I loved how it changed the sound of the truck.

 

hey whats up dude. i've been interested in getting some high flow cats but i dont know if i have to get all 4 cats or what? i was wondering if u could tell me how u set ur high flow cats up. and also what kind of high flows??

 

You only need to buy 2 high flow Magnaflow cats. ^

 

do u know what model or website i could get the high flows from?

 

And all I can say is DAMN!!! I also have a Magnaflow exhaust with pre rear axle exit tail. It is rediculously loud. I'm going to have to install a stock muffler back in. Now at 1500 rpm it sounds like most hotrods at 3500. A stock muff, will still sound impressive I'm sure of with the hi flow cats and pre axle exit pipes.

 

you can get them from performancepeddler.com and the part number is 94306

 

Sounds pretty damn wicked Andy

 

Thank you

 

our trucks have 4 cats? correct?

so my question(s) are

a) would i gain anything from removing the rear cats and getting high flows for the front?

b) would i still pass emissions with only two cats?

really want some new cats
i have a good feeling it would really **** off my neighbors

 

If you re-installed your stock muffler and tailpipe you'll gain in performance or just a better set up - 40's are just noise makers and torque munchers.

Removing all your factory cats and installing Magnaflow HF's can help Torque/Power/Mileage as long as it's got something good behind it.

You'll pass emissions with dual Magnaflow HF's - There compliant. If your just into noise - hack that 40 off and you'll wiz off the neighbors. IMO V6's don't sound good loud unless there built - sound better @ medium tone's.
