I have a 01 screw w/5.4. If i cut all four cats, run duals w/ a h pipe, and mils on the rear O2's. I was wondering if i would have any problems with this set up. I plan on doing it this week just see what you guys thought.

 

you'll lose fuel mileage but i dont know how much. make sure you get some vids of revving and a take off

 

No cats is probaly going to have a horrible tone. Throw some hi-flows on there.

 

x2. No cats sounds like s**t. Get hi-flow cats that volume it up to no cats sounds, but with a clear tone.

 

I dont know about aV8 but no cats and 40 series sound bad *** on 4.2 il find the link tommorow a guy has no cats stock y pipe into a si/do 40 with 2 tips going out before the rear wheel it takes a trained ear to know its a six.

 

Correct, V8 without cats = aweful. V6 or 4 bangers naturally sound pretty decent, deep and rich like, but with cats and a straight through muffler it sounds awful like most V6s do. Hi-flow cats and a chambered muffler is a good V6 exhaust.

 

yea i had no cats, H pipe, and true duals and now that i look back, i dont know why i ever ran without any cats, definantly made the right choice by gettin magnaflow hi flow cats about the same loudness as the no cats set up but still legal, and sounds amazing
