Looking to upgrade the exhaust on my 2001 Supercrew 4x4. I'm thinking of a Magnaflow SI/DO Muffler with High Flow Cats. Can someone tell me what part # on the muffler I need & also the part # for the high flow cats. Do I need 2 or 4 cats? If anyone is running this set-up please let me know your thoughts on it.

Thanks!!!

 

Depends on what muffler want. How loud do you want? What is your tolerance for interior drone?

If your going high flow cats, replace all 4 of your with 2 magnaflows.

 

I want something loud with a deep rumble but no glasspack type of mufflers. Don't mind drone at all.

 

My old Glasspack type looking Dynomax Bullets sounded deep and angry. Youtube it.

 

^ very true

 

Indeed!

 

Here is a vid I remember watching from way back to 2007 even. '02 screw 5.4 with hi-flow 94306 cats and 14" SI/DO.

Ah yes, one of the first vids I watched for the F150s hahaha... he's on here actually.

 

That is exactly what I want right there. Thanks!
